I CAN'T Do Some Things

My inability to play a picnic game leisurely caused me to question the belief I used to hold that I can accomplish anything humanly possible.  The other day, I went to a barbecue.  I saw people playing this beanbag-toss game (Cornhole).  I wanted to play, so I asked my friend to play the game with me.  Before we played, I took a few practice tosses.  I couldn't even REACH the target without maximal effort exerted on my part.  This phenomenon convinced me to quit.  I felt like playing a leisurely picnic game.  I was done with physical therapy for the day.  I just wanted to relax and drink iced tea, not try hard.  I can't run AND I can't play a leisurely game of Cornhole.
