Desire

The desires you have are your most important feature. It says a lot about who you are, and who you want to be.
If you ignore your innermost wishes, what can you hope to get from life?

Children never aspire to be solicitors, or to work in IT.
They want to be Police officers, Doctors, writers, photographers, sports men and women... And somewhere along the way they lose their vision. They stop chasing their desires.
At some point, our desires start involving others. What we desire is another person.
Maybe that's where we lose our desire... when we can't have the strongest desire we know of.
