Stubbornness, or perseverance in pursuit of a goal, is a key factor for the success of any business, individual or collective. It is very easy (and comfortable), but counterproductive, leaving a job in the middle, when difficulties arise, sometimes even very large, but require that persons higher application rate, effort, talent or just persistence.

Depression is a very common trend, but it reflects laziness and general lack of defined goals. It is an attitude to be fought with discipline and with a clear vision of the goal that you want to achieve. It is, moreover, the behavior of most people (the losers, of course), hoping that others meet their needs and wishes, for free, without needing to give any consideration.
