Don’t be afraid to fail. Don’t waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It’s OK to fail. If you’re not failing, you’re not growing.
A man can fail many times, but he isn’t a failure until he begins to blame somebody else.
Far better is it to dare mighty things, to win glorious triumphs, even though checkered by failure… than to rank with those poor spirits who neither enjoy nor suffer much, because they live in a gray twilight that knows not victory nor defeat.
