Life is short. Do not waste it. Do the things that will make you happy, even it's for other lives, it doesn't matter. If they meant a lot to you, their happiness is also yours. Never ever hold back, if you wanted to help, then go help. If you want to be part of everyone's life, go do good things especially those what please them. Life is short, you'll never know what the future are. Unless, you are me?
