Learning something new 
          Dos said, without being aware of it, my problem with learning something new is often a result of blocking myself from learning what I would like to learn.

          Blah, blah, blah you might say, well that is exactly it. Over time it is easy to develop prejudice or a cautious attitude about things. However, this can prevent you from learning something new, because it can act as a blocker.

          For example, it would be very difficult for me to become a Formula One driver, mainly because I have strong environmental objections to the activity. Besides that, I have no interest in being near very noisy things going very fast in a restricted area, where you always finish where you began.
