You're 30. Get over it. You're never going to have that cool job with that great start-up that goes public for a gazillion dollars. That ship has sailed. Even if you could find that company, convince them you're great, and get hired - the hours will kill you. Have a house? Say good bye because you'd have to move. Hope you don't have a wife and kids - because they don't last long with a startup work schedule. Are you independently wealthy or have a fully funded retirement- because otherwise you'll be screwed in 30 years. Working for startups that fail to launch means the stock options or ESOP plan is worthless. Do that for a few rounds and you'll be asking Slashdot: I'm 40 with nothing what can I do now?
Don't want to work for a startup? Going to try and work with an existing large corporation? Good luck with that. Those soulless bastards will fuck you over to make the next quarter's EBITDA. Look at all of the other posts where people are asking: " I've been in tech for 15 years. Who the hell do I have to fuck to get out?"
You want advice? Keep your 9 month a year jobs with pension and benefits. Use the summers to run a training/consulting business teaching people in local small business that they can use a VLOOKUP in excel instead of hand typing values into Excel 100 rows at a time. Use the extra money to buy a convertible. Go out and bang a 19 year old aspiring actress. Hell, bang two.
