Yes I read the text. Why the assumption that I had not ?
Transforming, overcoming, it's just a game of words here.
If you start out your career as an entrepreneur fearing failure then by acting you will accumulate experience which will over time give you the ability to deal with this fear and make it work for you.
Whether you want to call that transforming or overcoming is nitpicking.
If a marathon runner is afraid of losing and because of that finds the energy in himself to go a little bit faster thereby winning the race you could say that he has 'transformed his fear'.
But that's just wordplay.
There is a great deal of stuff written in ways that use words like 'transforming' to indicate something magical takes place.
In the end it is all just gruntwork and applied smarts.
If your fears push you to strive a little harder and maybe even make you succeed then you've just turned your basic insecurity (transformed if you wish) in to an asset. Others would simply say you've overcome your fears.
I believe that is a pretty normal process for any entrepreneur to go through, the ones that do not master their fears end up working for big corp. Or they try again in a couple of years.
Transforming vs overcoming is NOT just a game of words. When you overcome fear you do something despite your fear. Transformation can make you do something because of your fear.
In this case the act of having told people the course he was on transformed his fear from being a barrier pushing for giving up right away to a motivation to work hard and succeed. Instead of being something that saps motivation, it provides more motivation. And this switch tends to be quite rapid.
For a contrasting case of overcoming fear, a firefighter rushing into a burning building has to overcome fear of the danger from the fire. Even after the firefighter is in the building the fear still pushes for leaving the building. The lessons of experience may help with managing the fear rationally, but the fear will always push the firefighter to leave.
You don't overcome your fear, you transform it.
Instead of paralyzing you, it makes you run faster.
