I think the 4 most important skills are:

Curiosity - I agree with yours

Time Alone - You learn best alone, you work best alone, and you are most creative alone. Being with friends and family for me is a release from this pressure to avoid burnout.

Perfectionism - Just look at what Steve Jobs has done with a certain level of this. Your work will always absolutely be the best possible.

Competetiveness - You should WANT to be the best at everything you do. This will be what motivates you to spend that time alone pouring over new material, working through a hard problem. This will make you become a perfectionist if you aren't one because the perfect creations will be the best. I feel this is the most important skill to have because it enforces many other traits all at once.
