Making movies admittedly has less drastic consequences than most professions and allows for a lot of effects that make up for mistakes.
The thing I’m saying is, make use of the fact that you don’t doubt yourself too much right now.
As we get older, we get more realistic, and that includes about our own abilities or lack thereof, and that realism does us no favors.
People always talk about diving into things you’re afraid of.
That never worked for me. If I am afraid, I run away.
And I would probably urge my child to do the same.
Fear protects us in many ways.
Well, it can be a good thing if it makes you try things you never might have tried.
Your inexperience is an asset, and will allow you to think in original and unconventional ways.
Accept your lack of knowledge and use it as your asset.
