It's almost like some old feeling - some old teaching - is holding us back from it.
Maybe you can let yourself go to the happiness but then just minutes later you worry about the next thing. Maybe thoughts ring in your head: "You can be doing so much more with your time." "Did you have a productive day?" "What else can you be doing?" "That's not good enough."
Why don't we let ourselves have it?
Why are we not present for it?
Because we're so used to stressing and filling our every waking moment, our every break in thought.
So then how do we reverse this, how do we become present in our days? Present in our happiness?
