Do u look back?

Have you ever sat down or lie down by yourself, thinking of ur past ?? Be it today's matter or matters that were years ago, have you ever have a moment like that ? looking back, and then wished that those stuffs never happened ?? Or looked at the happy moments and be so proud of it ??

Well..... i do, and frequently too, almost every night when i'm lying on my bed, and the brain just goes thinking back of all the events that happened, good or bad, big or small matters, all will be recalled...... and i really hate it

When i recalled those bad things that happened, i somehow always realize that i could've taken another decision and nothing like that would happened, makes me feel so stupid, a simple stuff that just require a little more moment of thinking, and yet i was so quick to decision.... then now tell myself that i will not repeat the same thing again...

And the good things that happened, somehow we will not try and look at the bad side, we just wish that the particular moment can last longer or continue and never end, all we see are the happy times, and will not even bother to look into the bad sides even if there are bad sides in it..... it's like we're lying to ourselves, or escaping the matters which could make us lose our mood... but even if i did look at the bad side..... i'll just make believe that it is not true and move on and leave that aside, or just say it's not really something serious.....guess all we want to see it the good things and not the bad ones...

It's weird, we learn from the bad experiences, but not a really from the good ones... mistakes which leads to bad experience are usually the ones that make us become more cautious when making decisions, while mistakes which does not lead to bad experiences, we will feel that it's nothing really, and leave it aside, and even if we continue repeating it, we will not see it as a mistake... Or i should say because of the happy moments, we don't see the sad moments, but when we look at the sad moments, we recall of the happy moments....

So which is better ?? Which would make u learn more ?? Which one would u be willing to go thru ??
