You can only win in the game of life if you play. Those who stand and watch others don’t get to play or live life.
Some sit on the sidelines and watch. Some want to play but are too afraid. Others jump in and never worry what happens and some can fall into a mud puddle and come up wearing a dry cleaned tuxedo.
Most of us do all of these things, but not trying is the worst sin of the above. There is no shame in trying and failing if you learn and try again. Use what you learn and apply it to the next situation.
