getting better or worse?

sometimes we r trying our best in doing things better....but how can we be sure that what we have done is really the right thing for our life?actually by not thinking about the effect of it...we will do anything as we want...but then when we start to think about it...we will start to realize how the thing will effect our life ....the merciful Allah knows everything about us...only He can help us in doing the right things...hopefully i will have those blessing from Him...coz i really need it now
