Don’t wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.
Oscar Wilde said that if you know what you want to be, then you inevitably become it - that is your punishment, but if you never know, then you can be anything. There is a truth to that. We are not nouns, we are verbs. I am not a thing - an actor, a writer - I am a person who does things - I write, I act - and I never know what I am going to do next. I think you can be imprisoned if you think of yourself as a noun.
