Do you need a nap right now?  Cause I know I do!  Damn.  Sometimes life is so exhausting that you just need to step back and quiet your mind with some R&R and some introspection.  Self-care dammit!  Stop neglecting yourself and slow down and find your peace.  If you don't, you're going to experience burnout and you'll be wishing you had taken a time out when you could have.  

If you're in a position to not take any time for yourself?  For real, what are you even doing?  Nobody is meant to be "on" all the time.  This isn't a race or a show just how worthy you are in life by how much you do.  Who taught you that?  Because their opinion honestly doesn't matter.  So take the time out, rest, relax, and delegate!  Let someone else pick up the slack.  Oh, they won't?  Then just take the rest anyways, and see what happens.  I guarantee you, the world will not fall down without you for a moment.  It may not get done to your exact specifications, but that's something you need to realize.  It doesn't have to.  The world will still turn.  

Find a babysitter.  Delegate responsibility.  And get some rest.  The world will look different and so much better to you after you do.  And a less stressed out person is much more fun to be around, too *wink* LOL
