Definitely consider adding a booster to your confidence. Something that has a clear path of progression and visible results of your efforts. For me it was weightlifting. This confidence will transfer to all parts of your life and you will become a better thinker and person as a result. It will force you to find a way to get over your stutter as well. Anyone can DM me for any questions. I got over my stutter after 2 years of trial and error. I have a lot to share.
