In return you could leave some notes on the opportunity you did not succeed with and the next to try can gain from your experience.

This would be really great. Made me think of a game walkthrough where you get help on how to pass some parts that are not very obvious.

In retrospect, a person will always be able to identify "which" opportunity you took, even with pros and cons weighed in the moment this is not always as apparent.

Taking the opportunity to learn means being provided more information that might help in unexpected ways in the future. That is also why I might say learning if done right is not just a case of opportunity but should be seen as a necessity in your daily life, yes technically they are opportunities to learn but calling them that is like handing out loser trophies, pats on the back for nothing accomplished.

The opportunity is what stems from learning.

I think this may have turned into a disagreement, and this is not so, I agree with everything you said and it all makes perfect sense. Really great post and thank you again for joining Drop in the Ocean.
