“Ambition” is tricky. New grads become a “Senior Engineer” or a “manager” in 5 years these days. And most people don’t climb corporate ladder beyond a Senior Staff Engineer or a director. So you have almost 40 years worth of career left to climb two more levels.
Working your ass off continuously in pursuit of that ambition is pointless. If that’s the only thing in your life, then maybe it’s not, but ambition can be found outside of corporate America.
