Alone we came into this World, yet we bond with others as we grow, sadly not everyone we are attached to will be there when things gets rough and we need companions. That's when your best friends or even siblings forsake you in time of your dire needs, your parents might have died living you all alone to fend for yourself.
You need people to survive, but what do you do when those people deserted you?
Willpower, that counts more than a thousand friends, more than family and more than love. It gets you going when all is lost, when hope is just but like a candle in a Gust. That is where your ability to delay gratification comes to play, when you can resist short-term temptations in order to meet long-term goals and your capacity to override an unwanted thought, feeling or impulse which will save you from depression and suicidal thoughts.
Just what we need to survive...
