The biggest risk is not taking any risk.
I think a simple rule of business is, if you do the things that are easier first, then you can actually make a lot of progress.
If you just work on stuff that you like and you're passionate about, you don't have to have a master plan with how things will play out.
I started the site when I was 19. I didn't know much about business back then.
I like to pride myself on thinking pretty long term, but not that long term.
