I don't often see lists like the below. It's nothing 'amazing', but maybe the world needs less of the profound and more of the generous and/or simply kind. Because of this, something like Arvind Devalia's list of 29 Acts of Random Kindness (he calls it part of our Personal Social Responsibility, nice) is, I believe, worth checking out every now and then (my comments in bold).

1. Send someone a hand written note of thanks.
2. Make a card at home and send it to a friend for no reason.
3. Buy a lottery ticket for a stranger (interesting!)
4. Put some coins in someone else’s parking meter (good one! except in Malaysia people might take you for a hustler...) 
5. Buy a coffee for the man on the high street selling The Big Issue magazine.
6. Cut your neighbour’s hedge. (not much of these where I stay...we only have lifts, corridors, gates, etc.)
7. Walk your friend’s dog.
8. Give a compliment about your waiter / waitress to his / her manager.
9. Send someone a small gift anonymously.
10. Stop and help someone replace their flat tyre.
11. Let someone jump the queue at the bank.
12. Pay for the drinks on the next table at a café.
13. Treat a friend to the movies for no reason. (not so straight-forward, eh?)
14. Give a huge tip to someone when they least expect it.
15. Hold the train door open for someone rushing to get in.
16. Give up your seat for someone, not just an elderly person.
17. Write notes of appreciation at least once a week.
18. Talk to a homeless person and have a “normal” conversation.
19. Pick up some rubbish in the road which would otherwise be lying around.
20. Compliment a work colleague for their excellence.
21. Recommend a competitor to a potential client. (hmm...)
22. Give another driver your parking spot.
23. Give a piece of fruit to a delivery person.
24. Help an elderly neighbour carry the rubbish out.
25. Tell all your family members how much your appreciate them.
26. Leave a copy of an interesting book on a train / bus. (ah-hahh!) 
27. Buy an inspirational book for a friend. (I do this!)
28. Send a thank you note to a person who has helped you in the past.
29. Smile a lot.
