Some feel they know for sure. Some have considerable hope. Some are 50/50, and Some have just a little hope.
Myself for instance, I need to change my career to something more mobile. The training would take me 3 years minimum. But there's no way I'm going to bother if I believe I've got a few hundred thousand $$ coming my way!!
Sometimes one needs to make life plans, and deciding how much hope to invest becomes a serious consideration with huge potential consequences if you get it wrong.
That said, I've decided to have hope and speak well of the possibilities.
