Learn to learn
Early in life and in your career, it is vital to learn how to learn. This fact is counterintuitive to what you are taught in school; that you must learn from teachers. If you can only learn from someone else, then you will be a burden on those people. You'll find excuses for not getting things done. You'll slip into a fixed mindset instead of having a growth mindset.
Learning to learn frees you from all that. The limitation becomes time, which is a limitation, but you can also learn to manage your time.
