EGO

So many times has this ego come in between me and something I have really wanted to do, something as simple as saying sorry to someone, when I was really totally completely sorry but just dint says it! Or even at times smiling or saying hi to sumone.why should I (ego factor) and then there are things that I have done which I really dint want to but did them any ways just to boost my ego.I both ways I think I have hurt people. But this point is also valid that if u are nice to everyone all the time they tend to walk all over you.I cant figure out how to balance this, of course there aren’t written rules for this. Each scenario is different!
