Only those who do nothing make no mistakes. (Church sign board)
Because we dislike making mistakes, we might fail to pursue one venture or another just to avoid an embarrassing slip-up or the possibility of failure. Yet, deep down we know that errors happen to all of us, and the fear of failure will likely lead to failing to achieve. Work hard to avoid mistakes, but give your best effort at work.
Whatever your hand finds to do, do it with all your might. (Ecclesiastes 9:10)
