We are taught from such a young age that failure is abominable, punishable, looked down upon. . . when in all actuality it is a very necessary part of success. Nobody succeeds without many trials and errors or Failures! Fear of failure must never be a reason not to try something. In fact, we should expect to fail and fail again in the pursuit of finally getting it right one of these days!
So get out there and try again and again until you get IT the way you want it, what ever IT is!!
