I wonder how old the author is. I started working in 1997 at the height of the dot com boom. I knew people at multiple startups that got bought. People that were millionaires at age 25-30. I would get about 5 phone calls a week on my office phone from recruiters thinking I should leave.
In 2001 I saw all the layoffs and we had a reorg. The job and coworkers I loved turned into something I hated. No recruiters, no openings, it took me 10 months to find something new.
Since then I tried 2 startups and both were failures. In the first I don't regret it as my old job was not great. At the second I know that I made a mistake both professionally and financially. That was 5 years ago and if a recruiter contacts me for a startup I don't even reply. Not interested at all in the chaos and failed promises that was my startup experiences.
