Can you stay positive everyday?

I try to be positive with my thoughts. Even if I suffer something bad, I just persuade my mind by saying that whatever happens, happens for the good (and sometimes it does happen for the good). Recently I went through a good article on Positive Thinking. I think everyone should have a look on it. Its here: http://www.lifepositive.com/Mind/psychology/positive-thinking/live-healthy.asp

Positive thinking is very important. Negativity may be haunting us everyday, and yes, it does, but if we strive to stay positive, negativity will ultimately surrender and go away. Treat those negative things which had happened and cannot be revived as transparent. Since it had happened, it had happened, it is now past tense. Unless for those thing which can be solved, try on the ways to solve it. And think positively, yes, it can be solved. By doing these, it will allow you to stay positive all the way.

i have a classmate here that lacks attention and laughs to what i am typing. he;s such a stupid person and i hate him very much. but i don't mind him because i am a positive person. :) yesterday i have watched a movie that is entitled "the secret" and it basically states that we have to always feel good and everything will follow. :)

A person can be positive only if he is confident of himself and secondly he has an unmoving trust in GOD. If you have this then you can be positive every day .Negativity around us vanishes when we have the ability and belief that whatever goes wrong GOD is on my side and I have the ability to correct it. Once you start believing this I am Sure many a times you will be able to ward of the negativity around you.

think thing in the positive way make people feel more happy

actually, i constantly stay negative in my approach and views to the rest of the world. it makes it easier for me to see the good and positive.
