Why do we regret our mistakes?

We all make our decisions in our lives and first we think, that it's the best thing we could do. But after we get older and smarter only a few things stay under this label. Why do we regret our mistakes? Well the answer is easy, we keep to our decisions with out thinking again and again and again...
Instead of not thinking we all should think again about our choices. Is this really what I want to do? Do I really think this my self, or I'm doing this only because my friends and/or family want or don't want me to do this. It shouldn't make a difference in you choices if your family or friends like what you are doing or not. It's your life, never forget that.
Well for instance if I would have thought first and then acted I would now live a completely different life. After that mistake, if I would have thought again, then I would save me plenty of time and money. If after that I would have thought again I would now live in a different place and may be be happier? Isn't this every bodies thoughts now and then? I think you know what I'm talking about.
Remember no one is better at being you than you.
"Be your self. Every body else is already taken..." /Don't remember who first said that, but definitely not me/

Made a mistake? Think again! Did something good? Think again! You can be true, but you can make a mistake can't you?... Think about this and upgrade your mind and life!
