We were taught that determination leads to success. I sometimes can’t really see the difference between determination and stubbornness. Perhaps, when you succeeded, you were determined.
In the movie "The Pursuit of Happyness", Will Smith was determined. Because he was successful at the end. What if he couldn’t get the job? He was silly then. (and there would be no such a story) He could find another sales job and continued his stably difficult life instead of giving up everything and pursuited his rich man dream.
A friend of mine was crazy about a girl. He thought he could win her heart back. He is determined. What if what he was chasing after was only the "memories" left, but not the "real she" in the present moment? He is stubborn then. He knows that even if he and the girl were together again, the feeling won’t be the same because she has changed.
Andy Lau’s super fan was determined. She spent all her money, re-mortgaged her house, sold his father’s kidney - and all she wanted was to see her idol. Afterall, it was all not realistic and people think as she is just insane.
Maybe when you are after something which is "achievable" - you are determined. I sometimes imagine, what if a close friend of mine chooses to give up everything and pursuits an artistic dream, would I be supportive? These are the very old stories we heard from film directors, famous singers, and performers, etc. They started with pennyless - and they got the supports from their families and blah blah blah. When we heard those stories, we knew that they were finally successful. What about the vast majority who at the end became the nameless singers in night clubs?
Afterall, I guess it is personal choice. If a person is happy with chasing his / her dream, and without regret no matter what the result is, that’s fine.
