Each one of us cannot be great and do great things. However we can do the next best thing and that is to do small, small things greatly and become stress free and happier.
I get my inspiration from the wonderful saying that: if a litre of can holds a litre of oil that is wonderful! To expect it to hold a gallon is to merely become stressful. Most of us do just the opposite. We want a litre of can to hold much more than a litre. For example, we expect our child to stand first in the class and when this does not happen we get stressful. All children cannot come first.
