Figure out why before you figure out how. A good reason makes the hard parts less heavy.

A method can be looked up, borrowed, copied from someone further along. A reason cannot, and it is the part that holds when the work stops being fun. On a bad morning nobody follows a plan because it is well organized; they follow it because the point of it still means something to them. Without that, effort feels like a tax instead of a payment toward something.

Before you commit to the next big thing, write one plain sentence about why you want it. Not the version you would say at an interview. Keep it where you will see it around week three, when the shine wears off.
