Your deeds does not need acknowledgment and applause before it could become a good deed.
Sometimes, your good works would not recognized by those your works do not have direct relevance to. Others are blinded by jealousy.
We are wearing different lenses and different ear peices with varying volumes to respectively see and hear things.
The way you see a particular thing might be totally different from how I see the same thing, my best could be your worst.
Act simply because it is good in itself, not because it would be acknowledged and appreciated by others.
