How do I be a successful adult?

For context, I’m 17 living in a semi-independent children’s home run by my local council.

I genuinely have no idea where to start - I have my own bank account, I do my own laundry, I go food shopping and cook meals, I have a college qualification, but how do I begin?

I have a CV but finding jobs in the UK is really difficult - they often don’t get back to you and if you do have an interview they won’t respond afterwards.

A lot of support stops for me when I turn 18 so if anyone has any advice it is much appreciated 😌
