I would strongly recommend to focus on your strengths as your friend suggested. Working on your weaknesses will only drive you toward areas you are not naturally suited for, which is a reliable recipe for mediocrity. As for what you might be suited for, certainly, follow your excitement. Copywriting does not require you to use your muscle memory to project confidence, you can get the same effect by iterating over your wording. And it scales to boot! Finally, you might actually have better social skills than you think, but might not be among people who value what comes natural to you. I have found that to be common among people who value substance over talk: Talkers will be put off by your truthful analysis and define it as poor social skills because your insights make them uncomfortable. They might also consider you rude for not listening, while they simply have nothing of interest to say to you. People of substance will be delighted by your insights, and be interesting enough to make you want to listen to them.
