I worked for a Fortune 500 out of college for 1 year. That was 1996. I have been an entrepreneur ever since with some success and lots of failures. I have been a lone founder to employing 40+ people.
It's hard, lonely (most of the time) work but it's rewarding and invigorating. And you learn a ton (about business, yourself and life).
I transplanted to Manila (from SV a few years ago) trying to convince young local hackers to start their own or join my startup (the call of MSFT, IBM, etc. is strong in these parts). I have infected some young minds and plan to infect more.
If you are from the Philippines, give me a shout. Startup entrepreneurs are still hard to come by.
