I feel like I would be so much farther in life if I didn’t have a stutter.

I feel like I would be so much farther in life if I didn’t have a stutter. I started a new career, and currently I’m just thinking how much farther I would be if I didn’t have a speech impediment. I have more of a stammer, and it is exacerbated when I am nervous. I have social anxiety, so any unfamiliar social situation triggers my stammer. My self esteem has taken a huge hit. Networking has a huge impact on life, and often times knowing the right person can open doors that education, being genuine, etc. can’t. How do I stop letting my speech hold me back from being successful in life? And how do I stop feeling less than/envious of people who can speak fluently?
