An inefficient gold digger needs many good mines to extract a good harvest of gold. An effective gold digger, on the other hand, needs only one.
Learning is similar. You don’t need to have 20 years of experience to have sufficient learning. You can extract 20 years worth of learning from 1 year if you set your mind to it. Growing old is not an option but growing up by making the most of the experiences life throws at you definitely is.
So, while “am I learning” is an interesting question to ask in a situation, it isn’t terribly useful. Yes, you are learning something most of the time. But, asking yourself “am I extracting maximum learning out of this?” changes the game.
Just one trait about effective gold diggers – they don’t stop when they get one mine right. They keep working and widen that gulf. Learning is not different. Ask those who take time regularly to read, for example, and they’ll remind you that there is no difference between the ones who don’t read and the ones who can’t. Learning, like any other skill, needs work – perfecting it requires constant deliberate practice.
