Have been in the same position, my advice is to not quit (I did and I thought I could have had it easier)! You are in a great position now to make the next step

Have been in the same position, my advice is to not quit (I did and I thought I could have had it easier)! You are in a great position now to make the next step. Is taking a sabbatical an option? Do you have energy left after work to try something on the side? Find other companies. In the another thread I recommended the book "Why Employees Are Always A Bad Idea". There are different companies out there (building one myself).
