Think of the best possible thing that you could accomplish today, and then ask yourself this. What would be even better?
Instead of lowering your expectations to be more in line with reality, raise those expectations and then improve your reality so it matches them. That's a much better choice and yes, you can most certainly do it.
Realize that the best is yet to come. Then get busy and make it happen.
What has happened before may be interesting and useful to know about. Yet all of that is in the past, and right now the world is filled with brand new possibilities.
The quality of your life right now depends on how you live it right now. What will you choose to do with such a magnificent opportunity?
This is the moment when you can mold life into whatever you would like it to be. Take a deep breath, stand up, walk forward and truly live all the wonder that is here.
