Seth Godin writes “… if you learn a new skill, you own it forever.”
He compares the time we spend on different things to their long term value and the cost a fruitless activity might incur if it supplements a better activity.
Is browsing Facebook more valuable than an alternative, like learning about something you can use to improve things? That’s for you to evaluate and decide.
We have endless options of where we can put our attention but we don’t have endless attention. It’s finite.
That also means we can’t be 100% in hyper-learning mode all the time either. Our attention is finite and gets tired. Sometimes chilling and idling in mental neutral is just fine. It’s like when the capacitors in your stobes build a charge. The down time allows us to draw from our batteries for the next flash. Too many wasted flashes deplete our batteries.
