Yes, you CAN do this!
Over the course of my now long life, I gathered a Ph.D. in Psychology and a law degree [J.D.]
I practiced both professions in a variety of settings, including academia and private practice, on the east coast of the USA. I then moved west to Oregon and started into online life full time - writing, publishing, and course creating.
In all that I did, or now do, I work at helping others live their own best lives.
The courses you find here are the perfect outlets [for me] to put my expertise and experience "out there into the universe" for anyone - because - as I have learned in life - you never know who needs to, wants to, is willing to, or can learn something from what you have to say.
I've also had a many-decades interest in nutrition because I know it impacts every living thing - including people and pets. I'm not a nutritionist, but I mention this topic in most all I teach because it is that important!
Take a look at the course offerings......
I hope there is something here that intrigues you and helps you......
