always be happy

I agree, although there are times in life when worrying or being upset is quite normal, but that is ok because when we have those times we can appreciate the happy times even more and really be happy for being happy :)

en,i am an optimistic.haha ~

To be always happy is a goal in which every Christian aims. You are definitely right on target. Let's look at the positive side of things and what we can learn. Keep on the firing line!

i have observed that when our mind is free and happy, every good things comes to us and when our mind is bad every bad things come to us

It is difficult for some people not to worry. I have a friend who worries continuously every day and I wonder why is he always so negative, thinking of the worst that can happen. But maybe that is his way of coping. And he is a Christian. Personally I think if something is outsie your control there is no purpose in worrying about it. It it is within your control you can have constructive thoughts about how to improve or prevent the situation.

I don't believe in it...It's kind of obvious though that if you aren't going to worry anymore then you're gonna end up happy.Only time we are unhappy is when we worry about things that would make us so...Stop worrying=happiness.
