You should always ask yourself “what happens if this just doesn’t work out? What should I do?”
John Lennon wrote “Life is what happens when you are busy making other plans”. Believe it!
In fact, I think you can’t decide whether to execute Plan A, unless you know what Plan B is, so you can decide whether you could accept the alternative outcome.
Having a Plan B, puts you in control.
Of course this is a good practice for business but, for your life it is essential.
Do you have a Plan B?
