There is no shortage of advice around; books or web sites offering all sorts of helpful thoughts on how to live a good life, be happy, fulfilled. How to live without regrets.
I don't tend to linger on this sort of thing but occasionally something comes along that I think is worth the read, and worth passing on. Sam Altman, a silicon valley entrepreneur, programmer,venture capitalist and blogger, recently wrote something that triggered this reaction :
2) Life is not a dress rehearsal—this is probably it. Make it count. Time is extremely limited and goes by fast. Do what makes you happy and fulfilled—few people get remembered hundreds of years after they die anyway. Don’t do stuff that doesn’t make you happy (this happens most often when other people want you to do something). Don’t spend time trying to maintain relationships with people you don’t like, and cut negative people out of your life. Negativity is really bad. Don’t let yourself make excuses for not doing the things you want to do.
Number two is fairly standard, but still needs saying again sometimes, and pondering on occasion. Some other points he makes are more aligned with work, perhaps even the type of startup culture he moves in, but this culture also tends to infuse many more places that just Silicon Valley nowadays.
