Many years ago, I lost my job ad a dream company and I decided to become the best game designer I could possibly be. Part of this is still within me, also if many things changed. One for all, I understood that teams/clients do not need, nor want, the best in class.
If you are reliable, honest, candid, and humble, generally speaking you will be better welcomed into games teams. I notice, especially among junior game designers, the will to be better than others or more knowledgeable. You can easily end up being perceived as superb, like that.
The best way to do your job is to give the best of your “more or less”, without delivering too much. You will lose less energies and your job will be recognized in any case.
