I believe you can only do your best, but only you can know what that is.
One big problem is that some try and strive to be more like others and live up to their expectations and in the process lose their own identity. Why try and keep up with the distraction of striving for things that don't matter. In the whole scheme of things is striving for perfection, what ever that is, a positive contribution to society or is it a way of setting one's self up for failure?
