If you want to be a creator, photographer, video creator, entrepreneur, writer, etc. then you must gain this skill of starting. Start before you're ready. Take some action as you're learning. Because if you don't, no amount of knowledge or schooling will ever be enough.   

The truth is we're always learning. We should always be a student to our craft, but if you don't start, you'll never get anywhere, no matter how much you know.  

Hope this helps!
