I thought this could be interesting, mainly because I'm half expecting to hear a lot of things I hadn't even thought about and can hopefully learn from!
So what are the things you've learnt over the years that have been the most useful and had the most impact on you, style and beauty wise?
Mine would be the classic story of the size label not being important. Nobody sees the label on your clothes when you're wearing them and it's not a competition to fit into the smallest size. I wish I'd known this as an insecure teenager.
Also, that it's useful to know the 'rules' but it's also fine to break them, if you want to. I know what season I am and what colours I look best in but I also know that I love wearing black. It might not make me look my best but I'm happy wearing it and I feel good so sod the rules occasionally.
