Are you applying the 90/10 principle in your life ?

The link you included did not work, but I was able to find a pretty good explanation of the rule elsewhere, though I cannot copy and paste the link to what I found. Basically, ten percent of life is out of our control, things that happen cannot be helped. The other 90 percent, however, depend on how we react to things that happen to us. I think this is a pretty good rule to follow, though I can't say it is life changing for me because I know decisions I make are very important. I think I could be doing more to fulfill my potential, though I am afraid of consequences and taking risks much of the time. But I have noticed it is very easy to complain about things that can be changed. Instead of complaining, it is important to really look at a situation and try to change it.
