At any given moment, do you know what is going to happen 5 minutes from now? How about a week? Month? Year? 5? 10? Now, you may have a pretty good guess at what is coming your way, but can you say with certainty what is going to happen?
Probably not. There are an infinite number of things that can happen between now and 15 minutes from now. You are never able to know exactly what will happen from moment to moment.
Ask yourself, if you can’t really know what’s next, why do you sometimes expect the worst? You always have the choice between expecting or thinking about any choice and sometimes you pick the negative outcome. Sure, positive expectations are a part of life, but wouldn’t you like more? Wouldn’t you like to expect more in your favor?
Go ahead and do it. You don’t know what’s coming – you can’t know what’s coming. No amount of magic, psychic power, star-alignment, or lottery luck will make you 100% sure what is coming in your life. Expect the best. Expect something that is, at a minimum, favorable to you.
