Commitment, Yes Or No?

One the things that strike me the most is the lack of commitment in so many people. I immediately say that, in these reflections of mine, I am not planning to judge anybody or, even worse, criticize or condemn. I repeat for the ...th time that each human being has the right to be who they want to be, make their own choices and, of course, live with their consequences. But lack of commitment is something that I have a hard time understanding. Let's say that you are interested in learning Italian, or drawing, or cooking. You sign up for a class, you attend a couple of lessons and then.... you quit. Why? If we admit that the instructor is competent and the topics are up to your expectations, why do you quit? Another scenario: you say you like carpentry, so you decide you really need and want to build a bookcase. You start, all full of enthusiasm, but you don't complete the job. Or you start gardening, painting, writing the short story you've always thought about, going on a serious diet, then you stop haft way. Although these are not major problems and your life will not be jeopardized by your defection, nevertheless this recurring behavior may say something about your character. It may show that you are not consistent, that you are not reliable, that your decisions and your word cannot be totally trusted. It may also mean that you actually don't know what you want from life. So, how come that afterwards, when you are not satisfied with what you have and what you are, you complain, as if it were somebody else's fault?
