It’s easy to find reasons not to do it. Everybody can and most will.
You have to find what in you tells you to keep going or to take that jump.
Take the risk.
Do it, you only need one good reason and it’s that if you don’t give it a shot, if you don’t try, you’ll never know.
Don’t close a door because you found reasons to.
Close a door if you’ve stepped in and found out it wasn’t for you.
Otherwise, keep that door open and find one good reason to step in.
