Poorly written, factually incorrect, written to give the reader a small short-term motivational boost, soon to be diminished by the reality. It goes as far as to suggest that laziness, boredom and the particulars of the sort do not exist. Such big claims are supported by anecdotal stories, and occasional quotes from psychology professors, all convoluted in order to do say one thing: just do it.
> just do it. That's basically the only take-away from these kinds of motivational articles, and the only piece of advice that works. Once you start doing the thing you were nervous about, it becomes much easier and less stressful.
This is not necessarily the case. Sometimes you lack confidence with good reason because you are (currently, potentially will always be) unsuited to the task at hand, so you become nervous and stressed. There is nothing wrong with this either. Sometimes, it is worthwhile to persevere other times it isn't.
The hard thing is to know when to persevere and when to quit.
