You can want more without hating what you have. Those are two different feelings.

Ambition gets tangled up with dissatisfaction until people assume you have to be unhappy in order to improve. They are separate systems. You can be genuinely glad about your team, your job and your town while still working toward something bigger, and the people who manage both tend to last longer. Contempt for your current life is not fuel, just a worse mood with the same output.

Name three things about your life right now that you would miss if they went. Say them before you go back to the list of what you are chasing. Holding both takes a minute and keeps wanting from curdling into resentment.
