Run the chain on your own answer. Why do you want a better job? Better pay. Why do you want better pay? More money. Why do you want more money? So I can do this and that and the other thing.
At the end of the day it comes down to money. I am not going to pretend otherwise and neither should you.
So now be honest about what that means. If the purpose of this whole journey is purely materialistic, if it is money, then you have built the engine out of the one material that fails under heat.
The purpose is money. Things get hard in month three. What happens?
There will be a day you want to quit, and money will not be in the room with you on that day. It cannot sit with you at eleven at night when the code does not work and nobody has called you back. A number cannot argue with exhaustion, and it has never once got anybody out of bed at five in the morning in February. The reason people quit is almost never that they stopped wanting money; it is that wanting money turned out to be too thin a thing to hold a person up. And notice that this is not a moral point. I am not saying the person who wanted money was greedy or shallow. I am saying they were under-equipped, which is a different problem with a different fix.
And this works in the other direction too, which is the part people miss. Plenty of people have the knowledge and get nothing from it. There is an old image for exactly that. A donkey carrying a load of books. Every volume on its back is real, the knowledge inside them is real, and the animal is no wiser for any of it, because the load is on the outside. Knowledge without a purpose underneath it is weight you are carrying, not strength you have.
