You [are] always living for somewhere where you aren't. And while it is of tremendous use for us to be able to look ahead in this way and to plan. There is no use in planning for a future, which when you get to it and it becomes the present you won't be there. You'll be living in some other future which hasn't yet arrived. And so in this way, one is never able actually to inherit and enjoy the fruits of ones actions.
You can't live it all unless you can live fully now." - Alan Watts
