This, I Know For Sure

Over the past 35 years that I have lived, so many things have been learned, so many mistakes have been done, that whenever a calamity happens, I could actually calm down and say to myself:
'This is nothing. I've gone through worse.'

These are among my tried and tested life lessons:

1) Don't be greedy.
2) Don't take more than what you can handle.
3) Don't commit if you can't deliver.
4) Learn from the past, but don't dwell on it.
5) Cherish the present.
6) Cherish all the people who cherish you. After all, you never know if they'll still be around tomorrow.
7) Always say 'thank you', 'please' and 'sorry.'
8) You can't love others properly if you don't love yourself first.
9) Cleanliness is next to Godliness.
10) Once you've identified your key strengths and weaknesses, the world is your oyster, baby!
11) Light kills darkness. Love kills hate.
12) Time heals.
