Don't worry yourself too much over the future, move on from the past. Don't dwell on things. If you hold onto things from the past, it can just slow you down. Yes, some things cannot be forgotten, and some things may always seem depressing, but as long as a person gets up everyday and tries making a difference, tries doing good things, than good things will come eventually. Patience is the key.
Life can be bad, life can be good, life can be in between, but thats how it is for everyone.
There are good days and bad days, but try making everyday a day that is useful. You only live once, and since life is short, live everyday to the fullest. Say Lots of people ask me about my own personal romantic life. Anyway, personally, I've dated. Its good, but I won't go into it too much.
