There is no limit to the amount of good you can do if you don't care who gets the credit. - Ronald Reagan
We live in a time, where people are more worried about getting the credit than actually doing something for the good and welfare of other.
For example, our politicians fail to pass crucial legislation and agreements just because their political opponents could claim credit for it. No good will come out of such actions.
It's high time we start by ourselves and set example to others by doing good to others without having to worry about credit. At the end of the day, happiness you get by accomplishing something for the good of others is priceless.
