To do anything great you are going to have to collaborate.
Do you have an innate fear that collaboration is somehow going to divide your measure of creativity? I have this tendency, although in practice I have nearly always found the opposite to be true.
Healthy creative collaboration multiplies creativity and magnifies your combined imaginative powers.
This kind of creativity synergy (read) has to be fought for; we must battle against our own pride and insecurities to achieve anything greater than ourselves.
The very nature of creative collaboration is surrender and trust.
Loosening our grip on our own imaginations, allowing others to see what we see and looking at the same project or idea through their eyes.
