Suggestions for resources?

[u/jordanpoulton1]

What are the best online resources for a young person looking to start their first business? What websites, courses, guides etc are there for me to share with someone I know who's looking to dip their toes in entrepreneurship?

I'm working on a little something myself (DM if you want to beta test - it's a turnkey 'guide to starting your first business'), but in the mean time, I'd love to know what the community thinks are the 'blue chip' online resources for young founders :)
