my personal situation is: 45yo, just back to the corporate world after bankrupting my own consultancy company ( i shot myself on the foot with the tax and labor laws ) as a senior java developer. I fly circles around my 20-something teammates, and also around the tech team from our current client... became the de facto tech leader without even trying. Bad thing is, now i have more responsabilities than i bargained for, and dont't have that "workdays are just payed vacations" feeling anymore.
