One lesson that Aamir Khan's 3 Idiots taught us is that we don't have to follow the rat race to achieve our dreams. That lesson was substantiated in Phunsuk Wangdu, the scientist who had 400 patents to his name and was even sought by the Japanese! What we didn't know was that the character of Phunsukh Wangdu was actually inspired by an engineer from Leh.
