Focus on the right thing
A big goal for a lot of people is to get better at focus. And this is a worthwhile skill to practice.
But more important than that is to learn to focus on the /right/ things.
If you got really good at focusing, but you focused on unimportant stuff, you’d finish a year without anything meaningful accomplished. This is what a lot of people do: they learn to focus, but don’t take on the hard or scary things.
If you focused on one important thing a day, you’d make more impact than focusing on 10 less important things.
So the question you should ask every day is: what deserves my focus today?
What’s most important? What will make the most impact?
Then get good at focusing on that.
