I believe optimism and love are the key to life. Live life like you'll die tomorrow because nothing is guaranteed. Be the best YOU you can be, and never change for anyone but yourself. God put you on this earth for a reason, never think differently. Most importantly, don't spend a millisecond wasting your time on someone that isn't worth it. You'll never get that time back.
I often find myself wondering; who would miss me if I left this world.
