which is, to take easy.
You don't like his choice.
At his age, he is not capable of making such decision as you intented for him to make, nor does he need to.
What he needs is a sense of urgency: he needs to know one day he will be independent, parents are here to help him now but not forever, he needs to put more efforts into his school work and take on more challenging tasks. It's a jungle out there, and he does not have enough time to learn all he needs to before that time comes.
Do not do everything for him and remind him that he'll have to do those things by himself. Cultivate a sense of pride for things done in the right way. Praise for his effort. Engender a connection between happiness and a job well done.
Stop mentioning Bill Gates or Einstein, unless you want him to give up.
