"Don't expect anyone to be happy for your success or big dreams. If you have a loved one and a friend or two who are happy for you, consider yourself lucky." Other people can stop or delay your project or idea before you even act on it. So select your creative team carefully. Remain friends with lots of people but when it comes to working creatively, choose like minds and train them to be honest and unconditionally constructive.
This I have to remember too always:
"I say no to many things, so that I may say 'Yes!' to what gives me life." We need strong boundaries so that we have energy and time for our creations.
