I congratulate you. I love your post, the fact of facing your fears, getting out of your comfort zone, embedding your weaknesses into strengths.
In relation to the example you use with the English language, it is very true, if you do not dare, but you go for it, if you do not try, then you will never achieve it, you have to try, you have to do it, speak it, make mistakes ?, normal, make fun of your pronunciation, it does not matter, go on, there will come a time when you will achieve it.
The important thing is to do it!
