Не знаю, почему, но решил поискать автора. С первого взгляда очевидно, что это переводной текст, нашел оригинал:

Life is too short to wake up with regrets. So love the people who treat you right. Forget about the one's who don't. Believe everything happens for a reason. If you get a second chance, grab it with both hands. If it changes your life, let it. Nobody said life would be easy, they just promised it would be worth it.

Автор Harry Mackay

Оригинал нехило отличается ;)

А еще вот цитата попозитивнее:
Those who decide to use leisure as a means of mental development, who love good music, good books, good pictures, good plays, good company, good conversation - what are they? They are the happiest people in the world. -William Lyon Phelps
