why dwell on the past

I've had and have a pretty crazy life. Good and Bad times. I try to think about the good times more so only because it helps me think and be more positive. As for the bad times, I've had plentyyyy!!! But bad times are meant to happen. I can say I've learn from all the bad times I've had. I mean although I learned, doesn't mean I don't make the same mistakes. I know that sounds stupid, but I'm only human and I make many. Even if it's the same one. No matter what, I try to move forward and continue to be happy. I mean what's the point of continuing to dread over some BS that already happened. Guess what? It's toooo late noww, and complaining about what could've should've and would've been as no significance. So that's why one of my best advice is, NEVER SHOULD YOU EVER DWELL ON THE PAST, and  I will follow this post up with another blog speaking of the past but this time, somebody else past.
