Well I did my final flight just over 2 weeks ago. After 15 years of flying professionally, 20 years since I started with the PPL and in total 25 years in the industry I have just had enough. The changes that have come along with EASA are part of it, also I've reached the limit of what I can do career wise I think. I have no regrets at all but as previously stated, people change and I have. Life is short and there are many other things to go do apart from flying. I still have an interest in aviation, but I just don't feel the need to do it anymore. I must admit i'm not a fan of the PPL "scene" in the UK either. There are some good people but it is, at the end of the day, an industry that makes most of its bread and butter training people for licenses. They don't really care what you do after that. If you like bumbling around in a light aircraft then great, but if not (and I didn't) then it gets very boring very quickly. It was a means to an end for me that's all.
So, if you don't enjoy it quit. You can go back in later years if you feel you want to. Good luck.
