No one can go back and make a brand new start. Anyone can start from now and make a brand new ending.
There isn't promise of days without pain, laughter without sorrow, sun without rain, but can promise strength for the day, comfort for the tears, and light for the way.
Disappointments are like road bumps, they slow you down a bit but you enjoy the smooth road afterwards. Don't stay on the bumps too long. Move on! When you feel down because you didn't get what you want, just sit tight, and be happy.
