When I started out in sales, I wasn’t very proficient at all. But I learned quickly and am now very good at sales, and often give advice to others. What I did was asked tips from people lateral to me and up from me…meaning, I wouldn’t ask any colleagues for advice if I was supervising them. For example, when I was promoted to a senior sales rep, I asked either Senior Sales Reps, or Management above me for advice on how to better my self in the position I had. If you asked your subordinates for advice on how to do your job, I think you’d look a bit silly, and would deteriorate any credibility you had in doing your job. They’d want to ask themselves something like “Why am I not doing this person’s job, when I know it more than him/her?” I’m not sure exactly what line of work you’re in, but I’m sure you have someone in a similar position or title that you could go to for help, or perhaps the person that gave you this position.
