Have you ever heard of the expression “When  you fall off a horse, you just get back on”?  That’s how life is.  When something goes wrong just think “Tomorrow is a new day”  Also when I think of mistakes.  I think that if you don’t make mistakes you don’t learn from them.  Not saying you should plan on making mistakes.  But if u come across a mistake that you have made just brush it off your shoulders.  Meaning that next time you make that mistake, hopefully you can do something different or learn from that mistake. So next time you wont make that mistake.
