You cannot experience two things at one time. You cannot be in pain and in ease at the same time. Anger and joy do not co-exist in one moment. Tired and fresh are not able to share the very same space. Our attention is only able to fully experience one thing at a time. Choose what that one thing is. Nothing else exists in that moment.
What will your day bring your way. Be aware of the moment-to-moment switches your attention makes. If you embark on something new, your attention will be full of excitement one moment and full of fear the next. You decide. Will your life be an epic adventure?
