Tenaciousness is a skill.
During the course of the semester, I have learned quite a bit about entrepreneurship and the business world from both the text book, readings online (such as on Yellowdig) and real experiences (like interviewing people about a product). In order to keep up with the requirements (which - guilty as charged - I definitely did not do at the beginning of the semester), I found that you just have to plan ahead and keep on top of all of your work.
Tenaciousness is also about attitude
I suppose I have become more tenacious as the semester continued. I felt like a lot of the assignments did not teach me anything yet required a lot of time, but I persevered and did most of them anyway.
Three tips
For next semesters' students I offer the following advice for fostering skills that support tenacity and developing the 'tenacious mindset':
(1) Do your work ahead of time and review all of the assignments so you know which ones will take a lot of time and effort.
(2) When you get rejected don't give up. You learn from your mistakes more than you learn from your triumphs.
(3) Maintain the right attitude. A major key to success is confidence and the attitude that you maintain.
