When something feels scary, new, or hard, you can never go wrong by taking action.
(Within reason, of course. Breaking the law is new and scary, but action on that will have consequences...disclaimer complete.)
Starting a new project.
Taking up a new hobby.
Testing the idea you're almost certain will fail.
Learning a new piece of music.
Practice something difficult in a piece of music.
All of them lend themselves to procrastination, running, and hiding. So, we need to develop a stubbornness towards action. And encourage our kids to be stubborn towards action.
Rarely do people regret taking action on new things. But often, people regret the things they never took action on.
