why others do volunteering?

there are different reasons why people/corporations volunteer. companies encourage their employees for tax reasons, others to gain government incentives. some people do it to make use of their time wisely. while others to mend a broken heart. and there are plenty more reasons that you can find or hear. in fact, one of the reasons why i do it is to make use of my time wisely and productively. we can't turn back the time. it's best spent where others may gain. most people who haven't or doesn't want to volunteer thinks that it's all a waste - of time, money, and even future. but i say, it's not. actually, it's more of a gain - of friends, of learning, of insights, of personality. it changes you within. it makes you aware of the world you are in - cultures, languages/dialects, places, people, etc.. it makes you thankful instead of complaining. you also learn respect in different ways. i literally gained more, though not materially, but socially, emotionally, physically and spiritually. personality-wise it made me a better person and a citizen at that.
