Have you ever seriously looked into doing your own startup? I've been founding SaaS startups for the past 5 years and I can't go back. Hasn't been as lucrative (thus far) as FAANG would have been, but it's paid the bills and has been far, far, far more enjoyable than any corporate job.
Would be more than happy to give you my perspective and what it's been like as a small, moderately successfuly SaaS founder. Ping me at scottmas@altmails.com
