Have you ever watched people trying to park in a parking lot?
Most people circle around the aisles trying to get the close spots, waiting for people to load there car and back out. If nothing is open at the time they will swing back around and take another go at it, maybe get lucky.
Why don't they just drive to the back of the parking lot and park?
Why not just do that right away?
Park. Walk the extra distance. Get started.
Maybe this isn't the right spot. Maybe there are better spots out there to start. Better places to be in, more conducive situations. You might make a bad choice.
There are a lot of reasons to put off starting our practice. Even more reasons to prevent us from going deeper. At some point you just need to decide.
When do you decide?
