My 20s were very transformative years. I lived on my own for the first time, went on exchange to Canada for a semester, got a law degree, and then my first real job as a lawyer. There was a lot of partying, but I also experienced loneliness and insecurity.

I’m in my forties now, and in this video, I want to share 9 things I wish I knew when I was in my 20s. If you’re in your 20s now, I hope you’ll get some value out of this. Enjoy!
