I really don't want to do charity work with my friend. Does that sound selfish?
Not exactly. What else would you rather be doing?
I want to spend my time doing other exciting things that will make my life feel complete.
I think volunteering can add meaning to your life and make it feel complete. However, if there is something else that you'd rather be doing then that's alright too.
I think it's more fun doing different exciting things than helping needy kids.
Life is about balance. Do some exciting things, and if you're able, volunteer some free time to others.
