Reliability and steadiness are essential to any successful career, whether you’re a teacher, a doctor, an engineer, or a barber. That’s because these qualities are directly tied to long-term performance. You won’t achieve success over the years if you don’t stick to your principles, if you fail to learn from your mistakes, or if you regularly change your approach without good reason. We know this to be the case in our working lives, but when it comes to investing, studies show that a majority of individual investors do just the opposite: They unreliably change course all the time, and not surprisingly, the results are dismal. http://www.fool.com/investing/general/2013/05/16/why-investors-fail.aspx
