Teaching as an option for students in the Creative Field

I've always been a little nervous about whether I can actually become an illustrator & actually achieve what I want, especially with my demotivating lack of confidence in everything I do. My Dad always not so confident in me I always insisted that if I couldn't become a freelancer I would become a teacher. I didn't think there was anything wrong with the idea of it. And to learn more about it I attended Ursula Bryne's lecture on the matter.

She informed us what actual qualifications we would need to teach, how many more years that would take studying. And how whether or not it's really worth it if you're original intention was not to teach.
 Asking us questions such as "are you good with children?". In high school I did do a week of work experience working with a class of 60, 4 year olds. I hated it. Sure I gave them art lessons, but I became easily frustrated with them to the point where I said something very inappropriate to them & regretted it deeply. I think if I were to teach it would have to be at university level as my humour is too crude & dark. But let's face it, I don't have enough life experience to jump into a lecturer's seat. Even my illustration portray that I am not good with adapting to a younger audience.

In the end I learnt no, I can't teach not only because of my impatience with children, but because I don't want to allow myself the option of giving up on my dreams for a job I will hate right at the start of my game.
