It's easy.

If you didn't know it there is the life instinct and the death instinct.
The death instict is well a deadly one of course.
 
But how do we get the life instinct?
 
Here are some possible ways:
 
1.  Reinvent yourself.
2.  Look better.
3.  Clean your home till it's glittering.
4.  Have yourself attract people.
5.  Get passionate about some activity.
6.  Fall for someone.
7.  Make someones life a lot better.
8.  Dance often.
9.  Write a positive manifesto.
10.  Toss out all the junk you can.
 
I hope that helps.
