Dwayne Johnson aka The Rock gives an important life lesson - don't think that what you always want is the best thing for you. If something that you think is good doesn't happen, it can lead to greener and better pastures. Keep grinding.
My favorite line from this that is so inspiring is this:
"The best thing that never happened." When one door closes, another opens, but sometimes we get so hung up on what we think we have to have, be, or do that we can't see the forest for the trees. Pause. Give thanks. Reflect on what you have and have already accomplished. Make a new decision even if it is only to be okay with the way things are for the moment.
The best thing that never happened could be the place behind you while the newly opened door awaits your crossing the threshold.
