You can take risks on the job and learn as you go. If you have a good manager they will take your career goals into mind when deciding what you are doing on a per-sprint basis.

A great manager will allocate sprint points to you exploring a new area of technology as long as you can somehow realize value for the business as a result of that exploration.

A fantastic manager doesn't make you assign points to your work to fit inside an arbitrary time box.
