Your twenties are not a waiting room for your real life. This is already it.

Treating a whole decade as preparation makes it easy to hand over cheaply. Real life does not switch on when the job or the apartment or the relationship arrives. The years before that are made of the same material and count the same, even while they feel provisional. There is no later self that the current one is merely rehearsing for.

Take one part of your life you have been holding until things settle and start it at the size you can afford now: cook properly in the small kitchen, make friends in the temporary town. Provisional arrangements have a way of turning into the long ones.
