I am always ready to help people

Question:-
I am always ready to help and do good for another. Why is it that I never get any appreciation or something positive?

Answer:-

“The true measure of a man is how he treats someone who can do him absolutely no good.” ~

Your problem is that you are being too nice to people and they have started taking you for granted.If helping others pleases you then you must not stop and continue your steps as it after all helps you to become a better personality each day ! But if such acts cause irritation then you better not waste your good deeds over people who do not care to reciprocate.

So, be nice to people, but be nice repeatedly - only to the right people!
The worst regret we can have in life is not for the wrong things we did but for the thousands of right things we did for wrong people :')
Hope that helps !
