Many scientific studies have found that the taller you are the more successful you will be. A person that is 5.7ft is much less likely to be as successful as a person that is 6.4ft

There is no doubt that the taller you are the more money you will make and the higher position in employment you will command. There are exceptions to every rule but in the majority of cases, it applies. Another study has also found that most of the CEOS are well above average height or any other position of command such as a senior manager. So I guess your success is pre determined at least mostly anyway
