Wealth accumulation beyond financial autonomy is a silly pursuit. When independent, one should try to embrace what fulfils them, rather than trying to 'leave their mark' or 'stay at the top', by some function of narcissism or insecurity.
Chasing that image where you've "made it", where you've got the beautiful wife, a top job, living penthouse apartment overlooking over the city sky will leave you empty because it's a mirage. You'll achieve it bitter and toiled, having realised you've wasted a life chasing something that doesn't really exist because, once you have it, that won't be enough either. This dogmatic pursuit of idealised materialism, status conscious, is sad. We see it all throughout history and men once very powerful and now wise who've done the same tell us to do otherwise.
What's healthy is, instead of chasing this end, thriving in the process. The ideal is to enjoy the game. Those at the very top of the business world tend to tell us it's not about the money and it's not about the power. It's about the game. They could win or lose but the buzz of competing in that way has them hooked. It's about the process. If you're going to go this route, you need to do so being honest with yourself about whether you enjoy it day-to-day. Happiness isn't a goal to be strived for; It's being fulfilled on the journey towards that goal. Got to enjoy the game-- not just winning.
As a side note, this is precisely why the humanities are important. You can chase science and economics and engineering and you can conquer the world, indeed. The question is why and whether it will really turn out like you hope. Or will you reflect back with regret on a hollow shell of something you thought you needed to be?
