March on. Do not tarry. To go forward is to move toward perfection. March on, and fear not the thorns, or the sharp stones on life's path.
People grow through experience if they meet life honestly and courageously. This is how character is built.
The truth is you don't know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed.
The most important thing is to enjoy your life - to be happy - it's all that matters.
