Time Management

A friend asked: "Query: Are we, as Christians, required to do our best in everything we do?"

And this was my answer:

"I think that we ought to try to do "our best" but that "our best" doesn't mean our best in everything. We live in a world with responsibilities and consequences and we have to do our best to balance everything out. You can spend tons of time on any one thing, such one of several papers or HW assignments, and do really well on it but that means doing not as good on something else. One most apply the principle of diminishing returns because there is always a certain point where, because of lack of sleep or whatever other reason, that the amount or improvement gained is no longer worth the amount of work put into a project. When you reach that point, or because of time restraints before you even reach that point, you have to say 'I've done my best to put good work into this and balance everything out and I only had x amount of time to work on this so I'll trust God with whatever the consequences are.' and move on to whatever project is next."

What do you think?
