Just to do a follow up, since I'm the OP of this treat. I'm dealling better with my middle life crisis. I did an introspection of my way of living.
If I resume a bit: still with my familly, still at the same job, still doing pretty much the same thing, but viewing it in a different way.
If you look it in a diffenrent perspective, the job is only a way to bring food on the table, So I just drop it in my list of priority. I dont do overtime anymore, I do my job in a way that I'm proud of, NOT TO STRESS.
The familly is important, but you need to have some time on your own. I started to meditate, I spark some new projects, meet new peoples. But all thoses project have the same goal, developpe my inner self.
When your in a middle life crisis, it's because your looking the answer outside, you want to be fufill by some experience, you think your missing on something.
I took the road of fufilling my life with self discovery. And the more I explore, the wiser I get. Maybe someday I will find a meanning to my life on earth.
Good luck to you guys
