The goal is not just earning more; it is becoming someone capable of using more responsibly.

Capacity has to grow alongside resources or the resources create problems instead of solving them. More money, more influence, more responsibility all magnify whatever the person already is, which is why sudden increases so often go badly. The development is the real work.

Ask what you would need to be like to handle ten times your current responsibility well. Then build one of those qualities now, before it is required. Growing into it in advance is far easier than growing during.
