How can I liberate my mind from the need for logic and reason?

I am very creative and I used to be able to just do and let my imagination run my decisions and allow me to create and think freely. Unfortunately, as I have grown and learned more and more, I have reached a point where I need a reason to do something; I can't just do it for the hell of it. And if something isn't completely logically sound, I won't do it. The problem with this is I'm a musician and deep thinker. I need to be able to explore new ground. But if it defies some scientific law or if someone says thats impossible, I usually will agree and terminate my plan to create something new. This is a huge hindrance in my life. Do you think if Thomas Edison and had let someone convince him that putting light in a small container was impossible we would have light bulbs today? Well maybe someone else might have done it, but would if they too had be convinced the same thing? This is my problem, and I want to be free of it. I want to escape logic, proof, and reason- at least to some degree. How may I achieve this?
