Dedicated people don’t quit because they know that in reality backward is not a direction... why do I say this? Well, obviously the past doesn’t exist... that’s why... let’s say you had a significant event that happened that was a failure or what not.
If you went back to that event to try to relive it, that wouldn’t work, would it? I mean you can’t reassemble your old experiences with the people as they were back then to try and relive them... that will never happen.
As such you need to learn to keep going on any project you feel drawn to. Just keep at it.. because there is no reverse button for human experience... even though time does flow in 2 directions, we can’t easily access all that, so we need to go with the direction that we know works...
Moving ahead never hurt anyone ... so get going there, Padre...
