I love working on imposibile taks
I'm more interested in work that implies finding solutions to unresolved problems. I'm stubborn in trying again and again until it gets done. The beauty in this is that you have the chance to constantly improve your skills. But it comes at the cost of being prone to failure more frequently.
I've done easy jobs that implied just following some scripts. Not too much thinking, not too much personal input - just a human robot. But it's not for me. I got bored very quickly and saw how life passed before my eyes.
