You have all the time in the world. Age is irrelevant; more meaningless than a number.
There is no dream you now have that you will not manifest.
There is no challenge you now face that you will not crush and dispose of.
There is no point in spending one more second of your awesome, amazing life, thinking anything to the contrary.
Remember if you have control than you can change whatever it is you are worried about; if you do not have control, then you can manage your reactions to whatever you are worried about. Either way you are in control and time is on your side.
