This is how I live. Life is short. This is why I don't do "normal" things society expects me to do. This is why I spend 12 hours on a Sunday working on my book series (which involves way more than just writing), than going shopping or taking a nap. This is my passion. I'm just doing what it takes. Maybe one day I'll be able to do this full time, but for now, I do it at every possible opportunity and I'm grateful for the time I have. My constant urge to create something may seem neurotic but it is the only thing that gives me this euphoric joy, gives me a high I can't get anywhere else. Sometimes, I'm tempted to be lazy but then I think of how badly I want to hold a book I've written in my hands.
TL;DR : If you want something bad enough, you'll find a way. Don't waste your life just going through the motions.
