Do you check the worthyness before invest your time ?

Yes, before accepting a task, or before doing a task, i check to see that it will be worth my time, to do it, or to complete it. I think that if i am doing anything, especially on the internet, then i should be making something out of it, and not just wasting time. I try to stay on top of things by looking past the moment, and seeing what may generate in the future. Even in my studies, i look ahead, to see if i am going to benefit, by helping others with the same.
