Turquoise, I'm sorry but I misinterpreted your OP. I read it as "What advice would you give YOUR 20 year old self?" Obviously you wanted advice which would apply to today's 20 year olds, who already know that housing is expensive, Brexit's a thing and that studying ancient languages won't get you a good job unless you're Boris Johnson. I have a boy your age and I'm trying to get him motivated to acquire lucrative skills (he loves computers luckily) and to be more strategic about his finances with a view to becoming financially independent. I haven't needed to give him relationship advice because he's basically married to his self-built gaming PC :) but when I look back upon my life all my big mistakes fall into two categories. (Drum roll...) The first is not being intentional with my money, and the second is doubling down on bad decisions and not walking away from bad choices in education, marriage, family relationships and activism. If something is obviously not working, for god's sake cut your losses and
stop doing it. A third, trickier category of mistakes (and the point of my Ukip story) is being complacent and not taking threats seriously, but it's hard to translate that into actionable advice since you don't have a crystal ball and you don't want to become paranoid.
I’m 28 now and have only just started investing. I wish I’d done it so much sooner when I look back at all the money I’ve pissed away on takeaways and cocktails over the years grin
This! This is absolute gold, and exactly what I am trying to communicate to my kids. Investing from age 28 isn't bad, though: I was well into my 30s before I stopped spending all of my money as soon as I got it, and I've fallen off the frugality wagon plenty of times since. The key is to have a big specific goal in mind - moving abroad, buying a rental property, say - and that's more motivating than some vague sense that you "should" be saving money. Youngsters should read Mr Money Mustache and the free pdf of Rich Dad Poor Dad to get an understanding of the fundamentals of saving, investing and earning. I cringe at how clueless I was and how far ahead I could have got if I'd known what I was doing!
