Be careful. Take care of yourself.
But take a risk!
Get out of your comfort zone. Bend the rules a little.
Take a chance. Maybe it won't work. Maybe it will work out better than you could ever have hoped for.
If you don't take a chance, you don't have a chance. If you never try, you will never succeed.
Don't be afraid. You will fail, that is a part of life. It's what you do after you fail that is important. That is when you grow.
If you never try, you will never fail. If you never fail you will never grow.
This applies to photography as much as (if not more than) anything else.
