This is a great advice, but sales actually make sense for distribution partnerships such as gyms. To actually take on the point that you made around sales. I am an introvert who used to be nervous about people. There are definitely some people in this world who are naturally born salesmen and personally I hate these personalities :) It feels that they always hunt and they have an agenda. Now where it gets interesting is that the other 99% of people who actually learn sales, some will realise that sales is rather about listening and seeing a fit in a potential customer. You wouldn't want to sell your product to unqualified customer (someone who won't need it and will churn anyways). In terms of skills - you don't need to be pushy. After 8 years in sales I realized that at some point you will just develop a mental script and practice makes perfect. You will be nervous the first few times, but later realize that nobody will kill you for just a conversation. On the 20th call, you will realize its actually not that scary. On the 100th call you will have a state of flow where you already know what works and how to "feel people". On 1000th call, you will have a sense of empathy like 99% of people don't have. You will notice people have behavioural patterns and you will learn how to work with them as well as with people who are just negative from get go and how to cut them out early. These soft skills are invaluable for relationships, dealing with colleagues and many more. So the only advice I can give is: push through, get better, learn and continue doing so. I am pretty much on the same route with coding now :)
