the practical ability

We should have the ability to gauge our competence in a practical manner and not gloat over our capability and what we have done. The day gone by is history, hence there is no point in talking about it for future reference. That can only be considered as a past reference. However, each day is a new challenge on its own and we should be able to take on the challenge accordingly. The perception should be on what we can do and how, within the set parameters of the expectations.

If we perceive ourselves realistically, the results will show accordingly.
