It is said that every year only three to four percent of the total population on earth are courageous enough to start on their own. Out of that, I think only one percent successfully establish their business while the rest join the ever growing list of failed entrepreneurs.

Although every business requires a specific skill set and related domain knowledge, there are some general qualities which you must develop if you want to get going in any business. I say 'develop' and not 'have' because I don't think these skills are rocket science and if you've got the willingness, you can easily develop them and carry on your business in a better manner.
