Useful context: I'm 19. I stopped reading after the "Use your brainspace wisely." 

Overall impression: boring as stated :D

More specific feedback: 

• The tips seem very diverse (tips on relationships, mental health, physical environment, and learning skills were all under the "Use your brainspace wisely". It's unclear how they relate together. Thus it's confusing to read / figure out where you can find what tip. 
  • This could be addressed by having very clear headings. Ex: "Tips on Where You Live." Ex: "Tips on the Relationships You Develop." Ex: "Tips on Skills to Learn."
•  Tips don't seem valuable without stories/examples. This is most true for a young person who doesn't know of an experience about each tip. Ex: If you say "Get a mentor" - that goes in one ear and out the other. A more helpful way to say that might be: "Get a mentor. When I was working on a startup to do X, my mentor Y helped me figure out that doing Z was better. I was down to my last thousand dollars and changing course helped me save the company."
• I like when there were links to specific actionables. Ex: You can read this post if you're having mental health troubles, that post if you're looking for friend advice, etc. I'd love to see these links wherever you're aware of resources :-)
• I don't know why you're telling me these things. That is to say, the intention seems unclear. It's worth putting some kind of statement about the purpose of each category of tips under the headings. Ex: Before a heading on "Mental Health Tips," you might say "Young people are the most vulnerable to mental health problems. If we learn to work on these problems early, it makes them a lot less severe later in life. Here are some helpful actions you could take if you're experiencing mental health issues:"

I hope this feedback is constructive enough to give practical ideas on how to improve this post. Please feel free to let me know if something seems unclear. I'll do my best to give a timely response :-)
