A strong desire to do or achieve something, typically requiring determination and hard work.
People tend to have an unhealthy relationship with ambition partly because they use it as a cover-up for their insecurities.
Gary Vee:
Life is a joy when you have good relationships with your ambitions. I wake up every morning and chase my dream, yet I’m so not in need of achieving it. It’s a beautiful blend of conviction and humility. I fully believe I’ll make it, yet I don’t need to make it.
