I think a good portion of actuaries started out lacking that skill and some still do. How do you deal with it? Well I was thrown in the deep end by my 2nd employer. At my first job, my boss served as a filter, he got the requests, passed them on to me. I did the analysis, gave it back and so on. My 2nd boss felt that that would hinder his free time and so he made sure everyone went straight to me (and my co-workers). Worked wonders

There are places where you can go if you feel you need help (Toastmasters comes to mind).
