Self-Doubt

Tomorrow I go for an interview to transfer within my store to the "Showrooms" department. They sell kitchens, bathrooms and bedrooms along with all the peripherals. I've done this before but had to transfer out because at that time heavy lifting was involved and I injured my back. That was four years ago. I really enjoy the freedom my present job gives me (if I'm allowed to do it properly!). I would miss talking to people about products as varied as garden plants and electrical sockets. Or TVs and WCs! Or many of the other products in the store. BUT . . . showrooms staff get COMMISSION! Extra money! More for me to be able to support my kids with as they go through university. It's a big draw - but do I want to do it? Can I do it? We'll see ... perhaps they won't even offer me the job.
