You have a choice to make when it deciding exactly when to starting something.
Most of us want to start sometime in the future; a time when you will finally feel ready, when you will have your ducks all in a row, and the universe gives you some magical sign.
Or you can start exactly where you are right now.
The thing is, the first option is a false choice. When will you start the process of getting ready? Are you going to do that at some point in the future when you feel ready to get ready?
You have no choice but to start where you are.
So, what are you waiting for?
