Not everything is inside you, and that's a relief rather than a problem. Some goals need money, an introduction, a stretch of uninterrupted hours you don't currently own.
What is inside you is the part that goes and gets those things — the willingness to ask, to be told no, to ask someone else.
List what your goal actually requires. Mark what's yours to supply and what has to come from elsewhere. Then ask one person for one hour. That's usually where the missing piece is sitting.
