Why do I like to teach?

"I really enjoy teaching and training. I'm more than happy to have people learn from my mistakes or lessons learned and support them in their journey." 

What worked for me?

"What helped me in exam prep was the Bowen EHS course (its style - spread out with lectures and homework), the app and weekly questions, routine studying, and practice exams where I would actually sit for five hours."
