There are two jobs in a life

We can spend three days trying to anticipate someone else's decision and three years accepting something we could change.

Will they choose me? Will the work succeed? Will my children be happy? Will the future cooperate with the version of it I have prepared?

We replay conversations, improve old answers and run scenarios that are unlikely to be required. It is an absorbing hobby, although not a useful one.

At the same time, we can be oddly accepting of the parts of life that are much more available to us. Work that no longer fits. A week full of things we do not care about. A routine we complain about but continue to repeat with admirable consistency.

This may be one of our stranger habits: we try to redesign what is not ours to control, while inhabiting what we could redesign.

That is the problem at the heart of Design / Inhabit.

Design what can be designed.Inhabit what cannot.

It sounds like a tidier distinction than it is. Most of life takes place at the boundary.

The wrong mode

Imagine you work for a difficult boss. Your salary matters and leaving immediately is not realistic. So you spend your drive home replaying what your boss said, composing the response that would finally make them understand. You adjust your tone, explain your intentions more carefully and try to predict what will please them next time.

Much of this feels active. It may even feel strategic. But if the person has shown you repeatedly who they are, you may be spending design energy on something that has to be inhabited: their temperament, their limitations and the fact that, for now, they are your boss.

Meanwhile, you may be treating the shapeable parts as fixed.

You can document decisions. Ask for priorities in writing. Stop volunteering for work that will not be supported. Speak to someone you trust. Protect the hour after work from becoming an unpaid extension of the argument. Update your CV, begin conversations and build a route out.

You may not be able to design a better boss. You can design how much access that boss has to your inner life – and what you do next.

Sometimes you have to inhabit the boss and design the boundaries.

Inhabit is not another word for tolerate

This distinction matters. Otherwise, Inhabit becomes advice to stay in damaging situations with a peaceful expression.

It is not.

Inhabiting does not mean approving, excusing or abandoning agency. It means seeing what is already true, so that you stop wasting effort trying to make it untrue by force of thought.

Buddhist compassion can be useful here, provided it is not confused with limitless accommodation.

You might recognise that a controlling boss is frightened, under pressure or shaped by experiences you know nothing about. That understanding may help you take their behaviour less personally. It does not require you to pretend the behaviour is acceptable.

Compassion can include the other person. It must also include you.

Sometimes compassion softens your response. Sometimes it helps you set a boundary without needing to turn the other person into a villain. Sometimes the compassionate act is to leave.

Acceptance is recognising reality. Inhabiting is learning how to live there without handing it more of your life than it is already taking.

Design is not another word for control

Design has its own trap.

We are encouraged to design our careers, optimise our habits, manage our relationships and plan our futures. There is real freedom in recognising our agency. But design cannot guarantee an outcome.

You can prepare well for an interview. You cannot make someone appoint you. You can create a loving home for a child. You cannot design their nature or protect them from every sadness. You can make a treatment plan. You cannot negotiate certainty from a diagnosis.

Design deals with our choices and conditions. It does not give us ownership of the result.

At some point, life design can become an argument with life itself.

The boundary moves

What must be inhabited today may become designable later. You may need the salary now while you build enough financial room to leave. You may have to wait for medical results, then make decisions once they arrive. You may design a boundary and then have to inhabit another person's displeasure about it.

Design / Inhabit is not a once-off sorting exercise. The question has to be asked again as reality changes.

And the answer is often: both.

You cannot stop your children growing older. You can decide how present you are while they are still young. You cannot change what has happened. You may be able to change the meaning you keep assigning to it. You cannot make another person choose you. You can choose what you do with their answer. You cannot manufacture certainty about what comes next. You can decide how you spend the period in which you do not know.

We are almost never entirely powerless. We are also almost never entirely in control. Both truths are inconvenient. Together, they are useful.

An old question, with a second half

The Stoics drew a line between what lies within our control and what does not. Buddhist thought examines the suffering created by insisting that an impermanent world should stay as we prefer it. Taoist philosophy questions excessive force – the idea that life will yield if only we push harder.

Design / Inhabit belongs in that broad territory. I am not claiming to have discovered that we cannot control everything.

What interests me is the second mistake.

We do not only exhaust ourselves trying to change what must be inhabited. We also inhabit situations, habits and arrangements that are waiting to be designed.

We overdesign uncertainty. We underdesign our days. We try to manage other people's reactions and call our own repeated choices “just the way things are.”

The older question is: what must I accept?

The second question is: what have I accepted that I could change?

When I find myself circling a problem, I now ask:

Does this need designing, inhabiting – or both?

Sometimes I am trying to control another person, rewrite the past or extract certainty from a situation that does not contain any.

At other times, I have been calling something inevitable because changing it would be difficult, embarrassing or inconvenient. This is not the same as impossible, although it can do an excellent impression of it.

And sometimes the answer is simple:Accept this part. Change that one.

There are things worth fighting to change. There are also things we exhaust ourselves fighting because they are true.

The work is to find the boundary – and to notice when it moves.
