What is a good adjective that describes the quality of "having a growth mindset"?

I’m struggling to find a single word that conveys what is shared in the following statements

• Have a growth mindset
• Be a lifelong learner
• Be a student of the game

Is there a good single adjective that can communicate these in the sample sentence:

Be adjective.

(the most obvious is "Be growth minded." but that sounds odd to me and I’m hoping for a single word)
