I don't believe it is possible to find happiness in ignorance. The more you live to learn, the more you will learn to love life. There can be so much richness in life, so much to enjoy. Be true to yourself. Never do anything that you know that you will be ashamed of.
Life is already hard enough without having to carry the extra burden of guilt or shame.
Don't let your yesterdays hold your tomorrows hostage. Living without regret is the greatest freedom you can have. Make wise choices. Remember whatever path you choose in life, time closes the door behind you. Build strong futures.
