Have to broaden my mind !!!

There are soo many things I don't know... Yet, I tend to be judgemental of others.. They say, " One who lives in a glass-house should not throw stones at others."... Yet, there are times, time and again, when I am too quick to make my perception of someone or something without putting any effort into understanding how so and such came to be....I have always heard about the thing where it says never to judge a book by its cover... And I try my best not to do so. But then, there are times when I do not even realize but I had already ended up making my mind as to what so and such meant for me. And when it strikes me, only then do I understand that I was bit too amature and quick and wrong in my deeds. At such times, I question myself as to what gives me the right to even question someone else's actions or to decide on whether they deserve my appreciation or not. They are not doing it for my acknowledgement or my approval. I have failed to understand that the world does not revolve around me and my judgements and that irrespective of what I think or say or do, the world will still go on and they will still do what they do, be it for their own interests or for someone beside my pleasure. They have as much right to follow their aspirations and dreams like I follow mine and I have no need what-so-ever to be nosy into their business. But I still have not been able to make myself do that. I still make judgements, I still make mistakes, yet I tend to think that if they're not appealing to me, then they're not talented or important. We, as humans,( I do not want to generalize the whole of mankind, but this is what I think - another judgement...:s) have never really tried to understand someone else's position when we are on the higher pedestal, and we push them aside or make fun of them throwing away all their efforts down the drain just because we think their work isn't anything out-of-ordinary and rather unimportant, while in reality, they've put in all they could which is anything but ordinary, and still we are not considerate... I don't know how we as humans could have such constrained minds.. And I was no exception... Life's too complicated perhaps !!
