I have my regrets about the past but at the same time I know there's no point in regretting because it was a choice I hold no one else responsible for but myself.
Life is too short to wake up in the morning with regrets. So love the people who treat you right, forget about the ones who don't and believe that everything happens for a reason. Know a good thing when you see it and don't let it slip away. If you get a chance, take it. If it changes your life, let it. Nobody said it would be easy, they just said it would be worth it.
