Life is a gift, use it properly. Why to invest time on something that's not yours and never will be? Why to over think about issues which will never effect you even not in long run? Keep it real simple. Life shouldn't be long but big. Dream, work hard and achieve your goals. Travel, explore new things and find yourself. Don't just stick to relationships, its easy to touch someone's body but difficult touch soul. More than anything when the awful darkest days come, you will know you're not alone. Pain will tell you to keep quiet but that's a lie. Life is fragile and we all break in different ways. I hope you know that you can ask for help. Did you catch that? It's absolutely positively okay to ask for help. It simply means you're a human. We don't stop playing because we grow old; we grow old because we stop playing.
Never think you're always right because life has a funny way to prove us wrong. It has damaged, ruined people but wait.. They are dangerous because yet again life has taught them how to survive.
