If you’ve committed to a new project, congratulations! You’ve just started a new job. You can call this an informal apprenticeship, an internship, or whatever. It’s a job.
Even if it doesn’t pay you every two weeks.
Even if you need to work on weekends.
Even if it feels risky and unstable.
Even if it’s a part-time job.
Even if you get closer to the thing you want to do, but not quite.
Even if it’s just to pay the bills, in order to enable you to do the thing you want to do.
Even if you already have another job.
Some people work for the next paycheque. Other people work because they want to do a good job; they want to get as close to mastery as they can in the time they’re working. What are you going to do?
