Perseverance is an awesome trait, and real tenacity is a rarity in this instant gratification world. I deeply admire those who just keep at it despite incredible hardship. However, there are at least a couple of things I can think of that people need to be cautious about. 1) Not every venture has the possibility of a profitiable outcome. There is real wisdom in knowing when and how to get out and do something else. Often you can change the gameplan on the same venture, but sometimes it isn't possible. It is possible to waste your time trying to ride a dead horse. 2) Entrepeneurs often don't like to hear it, but there is more to life than work. It is possible to spend too much time and energy on your business. There is a long line of middle-aged (and older) men and women with kids that won't talk to them, spouses who divorced them, friends who wonder whatever happened to them (and even worse situations that I won't enumerate) all because they were so focused on never giving up on their business that they sacrificed their personal lives to try to "make it happen". Be tenacious, be determined, but be in control of your business life -- don't let it control you.
