Give some resources or tell what you do

Especially what if some random unwanted thought pop up in your mind ?

In a single go,For how much amount of time you able to maintain concentration?

If you do things you really want to do you'll find yourself concentrating wonderfully. Maybe there's something else you'd rather be working on.
