> You may have an idea that you know will make you a millionaire and which you could build, but you just can't force yourself to because fundamentally money won't make you happy and the idea is meaningless at best.

You can't force yourself to build the thing which will make you a millionaire, not because of nihilism, but because subconsciously it's much easier and more rewarding to have an idea that you hope will make you rich than it is to build the idea and know it doesn't work.

It's the same reason there are so many aspiring artists and rock stars compared with the number of failed artists and rock stars.
