(UK) I graduated from university this year and I’m planning on getting some experience in my career first, then might head back for masters - any advice?

I want to save up some money so that I can study and party with less or ideally with no stress. Given that I’ll be older I’ll probably be in a better place than most 18-21 y/o (I’m 21 right now), probably more muscle, money and that ‘older’/‘mature’ factor could come in handy.

Any advice/recommendations? Previously I commuted for my first year, second and third were all online so I stayed at home as well, went out few times but that’s about it. Now I’m playing catch up.
