Focus

Wise man said - nothing focusses the mind like impending mortal danger.

Or something along those lines. And how true.
Need focus in life? Want to know what you really want from it all? Think of 10 things you want to do before you die. List them, according to priority if you choose. They could be anything, from planting a tree to re-establishing lines of communication with a family member; from reading a particular book to talking to the Pope. As you keep identifying, focussing and achieving, you gradually separate the truly important from the merely interesting. The method from the madness. The emotion from the music.

It works wonderfully.
