Oh, I suck at discipline... in a manner of speaking. Meaning that I draw complete blanks and dry spells and then suddenly "vomit" great gobs of creativity for a few days.
Where I have found discipline is saving and spacing out the ideas from those creative outbursts on some sort of a regular schedule.
It does seem like we live in a world governed by money. Even if I don't worry about it, it's almost impossible to not have to interface with that money-driven world somewhere along the way... I'll be the first to admit that I like electricity and indoor plumbing.
