Some great advice up above...

First off, take the Apple angle out of the equation here...

Do you really want to work in retail sales? You have to be a real people person to be a successful salesperson and like a lot of routine. Sure the products change slightly and the customers have different faces but shelfstacking, inventory, cashing up remain the same day after day

Before you look at any careers, try to figure out what motivates you (not what you think you should say but what actually matters to you). Do you like routine or are you better doing lots of little things? Do you want to be an expert in one field or would you rather be simply good in many fields? Do you prefer thinking things through or reacting to opportunities? Do you like a lot of leadership and control from above or would you rather be your own boss?

Once you know what your personal skills really are - you can figure out what aspects of different jobs turn you on or off and then work out what course you want life to take for the next few years.
