Be slow to criticize and fast to appreciate.
We criticize when we are seeing the negative aspect of something.
We appreciate when we are looking at the positive aspect of the same.
Being negative brings a grey shade, a dullness whereas
being positive brings happiness.
It does not mean that we should not take notice of both the sides,
It just means that we should appreciate the good and try to instill it in our self plus high light it.
And we should also bring to light the bad side, in a positive way, so that it can be improved, as there is always a scope of improvement
