Why think about interests, hobbies & work?
They are likely to be the things that set you apart from other candidates for the job / college course
Like what?
Things like school sports teams / clubs, part time work, scouts, guides, sports clubs,, football teams, interests, hobbies, Duke of Edinburgh, volunteering, working with family army cadets & sea cadets
I already do plenty
Splendid, note down all the things you do and how they could help with work e.g. working in a team, independent working etc. Also, think about getting a reference from someone who runs the activity.
I only play games consoles
It's not too late, get out there into the world and do something you can talk about with future interviewers
