Get a journal started. Write and take notes, preferably digital notes. Get your head clear on what you’re trying to do. Maybe there are people out there who can execute a big undertaking by just bumbling forward on the thought/motivation of the day, but I haven’t met them.

Perhaps you’re trying to save time by asking others where to start, but I advise you to get used to making judgement calls on where you ought to put your attention.

Slow down and settle in. Work on it a little every day. Record your progress. Learn and practice.

And go easy on yourself. Everybody starts somewhere.
