Thank you for this post, I think it will be really helpful for so many people in the online community in this forum. I also finished school a few years ago and I remember that I put a lot of pressure on myself and everything was very overwhelming, but in the end, everything turned out okay.
I love these 7 tips/advice you mentioned I think the two most important points are to just enjoy yourself and that it is okay if you don't have everything figured out, even in your 20's! Everyone is on their own path and it is not a race. It's important to take things one at a time and not put pressure on yourself to succeed.
