Sometimes a small subtle shift in our language is all that is standing in our way. Align your language with your desired positive outcomes - what you DO want - not with the potential downside of the activity.
Instead of... What if they say NO? ask... What if they say YES?
Instead of... What if it doesn't work out? ask... What if it does?
Focusing on what you don't want leaves you building your defenses, leaving you ill-prepared to take advantage of opportunities that arise. Orient your brain to focus on what you do want, to get it working on moving you forward.
