Your most powerful question to encourage you and others to take action is “when?”. It really nails you to avoid procrastination and reduces stress. You and they now have a date in the diary and can take it out of your “to do list” and swilling about your brain.
I enjoyed Ian Cooper’s simple but effective book “Just ask the right questions to get what you want”. Move quickly past the first slightly superficial section into the meat of the book and the tips are there to use immediately. Sound common sense which is remarkably “uncommon”.
Go on – just ask!
