Denial?
Disbelief?
Doubt?
Distraction?
Walk through one of these and it’s quite hard to get back into the room where you cultivate your dreams.
Why have any plan that distracts from plan ‘A’? You don’t want that temptation and your dreams don’t deserve that either.
When we’re talking about your dreams, an exit strategy is an oxymoron. Nothing more. Nothing less.
