If you are like me (super shy and self conscious) I definitely would do toastmasters first before doing a lot of teaching. I did teaching for a while but I wasn’t ready so I just kept piling up more and more bad experiences without getting better. After a year of toastmasters I had a pretty good foundation and finally could actually improve.

It feels like going into a country without ang knowledge of the language. You can be there for years and never learn anything. But once you have a foundation then learning is possible.
