Decisions, too many careers and no direction

Muse, typically a person considered to inspire great things in other people so why can't I be one. I hear from my family constantly that I have an overwhelming amount of ideas but with no direction. Wondering the earth with thoughts and ideas but no where to put them to use, I should be a muse. Over the past three years of my life I've thought and prepared to start over six businesses, I mean detailed them out to the point where if I had the collateral I could completely get them up and running. Same goes for my writing, I've started four different books and each are now respectfully sitting in their own binders waiting to be finished. At first I thought maybe I'm just not seeing these projects out, I don't have the motivation to finish them. Further thought lead me to believe or maybe talk myself into that something just always came up or a better idea popped into my head to jump on. Needless to say, this course of action has not gotten me very far. So, with that staggering realization dawning on me I know I need to make up my mind and get on track. Ultimately the point is to take a path that can gain considerable income or at least a livable amount with the bonus of contentment in a daily basis at work. Economically any self started business is an uncomfortable risk, today's idea might seem substantial, tomorrow not so much. At some point though if you want something you have to just take the leap and hope your shut opens. So, here goes to jumping and finding my place.
