I believe in karma, I know that if I do a good deed for someone, someday another person will do the same for me.

yes... give a word of praise make a good reward.

Hello Elvis, No you shouldn't because while some would appreciate some wouldn't ,and that might disappoint you. If you are doing a good deed you have to be convinced of doing it ,it must be satisfying you personally regardless from the reward or people's reaction.

If you expect to receive a reward for doing good, don't do it at all. If you want to get reward for doing good, might as well work for it. For it is better to give than to receive...

To give more value to your good deed you shouldn't expect someone to reward you just do good things and forget them otherwise you would be arrogant!
