Grow a habit of checking some (any) system first. BJ Fogg's Tiby Habits program is a good start. And make sure it's a tiny investment of time/energy at first so no full-blown complex planning right off the bat.

Generally reading 'Making it all work' from the GTD guy also helped with just wanting to get everything into some system; which I developed bit by bit using tiny habit changes.

By now I have an amazingly complex system involving a Google Sheet, Workflowy and Evernote that would be just about ready to be turned into a professional product... but getting there I went through dozens and dozens of little improvements of just getting everything out of my kind and into some system.
