My friend I am in the same way. I am about to be 30 soon, working 1 - 2 hours 95% of the time, 0 calls or meetings that I don't dictate, no manager / quarterly reviews / 1on1s / etc.
All this while making north of $300k, and I still am not satisfied and looking for more. I grew up poor on food stamps and busted myself for minimum wage and was happy. Now I'm here with almost no work, lots of respect at work, great pay, big house with pool, and I just feel like I want more.
