No. I think you have to enjoy it, if you want to do it long term and not burn out.

Do what you enjoy. Be happy and have fun. You're not hurting anybody by being a do-gooder. You're actually helping people, or trying to anyway!

When I was heavily involved in a volunteer org, the main reason was social activity for my depressive, self-isolating personality, and feeling good about myself.

I'm not sure that even Mother Teresa would qualify a pure-as-the-driven-snow altruism test.

Doing good is doing good, no matter what your motivation is. Of course, it might be even better to do good in a different way, but that doesn't make your charity less helpful.
In Judaism, we have a ladder of giving which goes through a few different types of giving and ranks them based on your motivation and the end result. But all of them are valuable and any way you give is good.

As long as you don't lie about it or use moral justifications as rationalizations or worse.

Oh, here is a better explanation of the ladder, if you are interested:

1. The lowest: Giving begrudgingly and making the recipient feel disgraced or embarrassed.

2. Giving cheerfully but giving too little.

3. Giving cheerfully and adequately but only after being asked.

4. Giving before being asked.

5. Giving when you do not know who is the individual benefiting, but the recipient knows your identity.

6. Giving when you know who is the individual benefiting, but the recipient does not know your identity.

7. Giving when neither the donor nor the recipient is aware of the other's identity.

8. The Highest: Giving money, a loan, your time or whatever else it takes to enable an individual to be self-reliant.

According to Immanuel Kant, yes. According to anyone else in the world, no.

I actually think people who are do-gooders because they think they "should" are on the wrong path, and may even end up creepy. I'm a do-gooder because I find it more interesting and meaningful than other paths -- not because I'm focused on Helping.

"Pretend to be good always, and even God will be fooled." -- Kurt Vonnegut

rmless2, that is so interesting! Thanks!

Doing the right thing for the wrong reason is still the right thing, or else it wouldn't be right, right?
