> My idea of 'hard work' has changed a lot since then.

I'm a phd student and my idea of 'hard work' has changed a lot since I started, too. The master's was child's play. Now it's about determination and finding avenues forward when facing problems that are so large that even finding a good question to ask is a major success. Staying up late and putting in the hours is the easy part.

This is not as simple as you imagine it to be.
