cheer full life...???

I read it somewhere, we are not happy because the outcome is different from our expectations. Sometimes, we expect too high or we expect something that will not happen, hence we always feel upset when the result doesn't turn out to be what we wanted. We just gotta understand nothing is perfect in the world, and everyone thinks differently, not everything will follow what we want, slowly accept the facts even though it's not what we expected. I was once really stressed at work, almost have depression issue, I just kept telling myself that work is just work, I shouldn't take it too personally, though I always want to do a good job. Try to accept the facts and live in the real life, then slowly I become more cheerful now. Hope you'll find a way to get rid of the tension at work.
