Stuff happens. None of it is really 'good' or 'bad' but rather we either like what happens, or we don't. Now of course, y'gotta admit that there's an awful lot of stuff that nobody would really WANT to happen... but then it's going to happen anyway.
While you might argue that some people are dealt better hands than others, none of it really matters. It's all in how you play the game. You really only lose if you sit there and complain about the cards.
Our present moments are the results of our past events, and even more so the results of how we dealt with those events. Good, bad or indifferent... they all got us HERE.
So the future is dependant on what you do Today with all your stuff. Going through some negative experiences? It happens. Move through it; Learn from it; Grow out of it.
Take it for what it's worth... turn it around... and you can make it worth so much more tomorrow.
