The Valve

My idol would be one of the founders of The Valve Cooperation, Gabe Logan Newell A.K.A. Gaben!

He was a student at Harvard when he decided to drop out and then worked for Microsoft!
Which he then left to make the Valve Cooperation which I absolutely love as they have made the game client Steam, which is home to so many of my favourite games.

And also a very iconic game half life!

Gaben has built his way and even then it's for the enjoyment of the masses, which is what makes him my idol.
