I want to be a French fighter pilot. Any advice?
The third point in your original list is a clear red flag:


  I'm a huge fan of airplane (but I'm not the type of guy loving learning every thing by heart)


I don't mean to put you off with what follows, but honestly, you've got to love learning everything by heart in the military in general, let alone the airforce.

Becoming a professional pilot is demanding, becoming a military pilot even more so. Both require high intellect, the ability to learn and memorize things easily and preferrably, especially in military aviation, a burning desire to do so.

On top of that, to make it as a military aviator, not only do you have to be enthusiastic about aviation in general, but you have to have just the right mindset: utmost dedication for the military way of life, deep patriotism, and absolute altruism. Any succesful military person is first and foremost a soldier, only in addition to that can one be something more.

The guys and gals at military aviation operate on a whole different level from an average pilot. You simply are not going to make it if you are not all in. About aviation and more importantly about military.
