Regret kills the spirit. It’s like the old saying goes we will regret the things we don’t do more than the things we do. Sure you can make the argument that bad decisions in your life were decisions that you had rather not made, but had you never made them you would never learn, you would never understand correct alternatives, and you wouldn’t be able to advance in your life anywhere forward than your current standing.
You see regret is something that seeds in quietly and doesn’t rear its ugly head until you reach a point in your life where life reveals to you the realization that the opportunity that you walked away from was the biggest mistake of all. You can’t avoid it, it’s life.
