This is
true of most of our suffering. Don’t believe it? Go ahead and observe the kind
of thoughts you project, predict, play and replay in your mind. Observe how
much you may be living in your head instead of experiencing the present moment that is right in front of you. 
The what
if’s, could have’s, should have’s, they all live in your mind, they don’t
really exist in reality… They may exist in your head because you think it so,
but that doesn’t make it real—at least, not yet.
Anything
that lives in your head is only but an illusion that can be made real by your
actions in the present moment. Perhaps it would be wise to get out of living in
your head and practice turning your attention to the present moment
Make a
conscious effort today and everyday to choose thoughts that will serve you better, and be “here” (not in your head) to make choices that can
take you a little closer to the things you want, rather than just
“think” about the things you do not want.
