You know what I've found? Another way to get started is to stop THINKING and start DOING.
It's easy to over-think things. We go back and forth, "Should I do this or this? Is this better or that?"
In the long run this indecisiveness - this quest to have all our ducks in a row before we go - just delays action and doesn't necessarily guarantee better results.
It's SMARTER to be a STARTER and and course correct along the way.
What is ONE thing on your mind you've been wanting to do? Don't just want it. Start it.
