I would say it's eager to learn. As long as you are willing to learn, you will be able to excel in every scenario. From my experience, 3 years back I knew nothing about digital marketing, but I put in effort to learn to pick up the necessary skills. 6 months down the road I manage to generate 400K revenue via funnel and marketing automation.

Grit.

I'd say a couple of things work together:
1. Develop an inquiring mindset where we ask open-minded questions (that challenge our own assumptions) to ourselves and others
2. Get into a resilient mindset where we use our self-thoughts, emotions, self-talk and actions to keep ourselves in a positive state of mind.

This helps us to use our resources more creatively, bounce back from unsuccessful ventures and develop great relationships to help us succeed.
