You need to be mindful of the fact that a question such as this will illicit a lot of projection from people based on their own experiences.
No, you’re not unemployable and no you actually do not have to take whatever work is available and get stuck in a rut of continuing to not break into a career job. Unless obviously out of financial necessity. In which case, obviously, you absolutely do need to take anything. If you are have the privilege of not having to- then I don’t understand how taking anything will be good for you at this point. I’d focus on breaking in to what you want to do and maximising. No, working in a warehouse won’t necessarily make you more employable in your industry of choice. No, at 24 years old you don’t have to overly worry about a career gap. No, your peers are not wildly ahead of you as has been suggested. Yes, you do indeed have the opportunity to select a career of choice - - but you have to work very, very, hard at this part.
You need to buckle down and make moves to add to your CV. This means INDUSTRY SPECIALISATION. There is loads of CPD (Professional Development) and courses you can do, both for free and at a small cost that will help you crack in to your industry of choice. Any undergraduate degree you need to think of as the baseline. The foundation if you will. What will help you now is of course practical industry experience but also taking real initiative towards skilling up and learning. You’re more likely to get industry experience if they can see you’ve skilled up or taken initiative to learn about the specific industry. NOT just general academic stuff.
There are coding courses, Princes Trust courses, charity volunteering. All for free that you can do. You really need to be looking at this free stuff and jumping on it. The support IS there for young people to get on the path to what they want but you do have to capitalise, commit, treat it like a job and work hard.
I’d agree with the points about being flexible with what you want but I’d caveat by saying at minimum selecting a broad industry to specialise in is essential. You need something to aim for otherwise you’re directionless.
FYI general point: starting a business is an option here. There is LOADS of support for this. Look at the Prince’s Trust again. More young people should be excited about this option.
Be positive. It’s a horrible time now but this is an opportunity for you to build resilience. You’ll be fine long term - nothing lasts forever, good or bad. @I hope you’re well supported at home.
