Have you ever had a situation where you have decided to do something and then something better comes along? For example, you decided to buy a notebook (or a car, house, whatever). After you bought the notebook then a newer and better notebook (which cost the same or even cheaper) is available. You hate yourself.
I have had many occasions in which I have decided to make a "gig" (presentation, training, workshop, teaching, etc.) on a certain date. Then, a better offer (bigger audience, better pay, bigger impact) comes along on exactly the same time. What to do? I have made a committment. Well, I have no option but to decline the latter offer. I hate myself for that, but promise is a promise. I just have to do the best gig ever!
This is also a common theme in a song. Boy meets girl. (They think) they fall in love. They make committment to each other. Then, the boy meets another girl (or the girl meets another boy). She or he is better (prettier, more handsome, funnier, more understanding, richer, all the good things). It is too late. They regret it for the rest of their lives. (Song fades away ...)
Have you had this experience?
