What makes your day? Getting a surprise increase in your pay check? How often that happens? Getting completely bladdered with some mates? You get a headache the next day...
If you can help someone in need and the person turn round and say 'thank you'... Does that make you feel good? If you've done that recently and it really does make you feel good, you're already doing something to improve society.
If you don't know what I'm talking about, you should stop being so selfish and rethink your attitude towards life and your place in society...
