Delayed gratification and procrastination
There was a famous research study conducted years ago that involved young children and cookies. If the child could wait with a cookie in front of them, then they got another cookie. Apparently the children who delayed gratification, and thus got an extra cookie, were more successful later in life.
I judge myself to be good at delaying gratification, both by my nature and by my training. But at times this seems to intersect with an adult tendency to procrastinate. Sure one in the hand are better than two in the bush, but what if I believe I have a plan to get the two in the bush? The plan suddenly becomes more attractive than one in the hand, even though it is not yet realized.
Where are you living in plans instead of the present reality?
