What should I start with?

I'm nearly lvl 15 and got to know the game a lil bit now.
When I can fly where should I start? And what should I start with?
Like buying stuff and selling but what do I buy where and where do I sell it?
Thanks for the answers

flowers and plushies.

Hey man!

So I got almost all of my advice when starting out from Baldr's guide:

For tips on flying specifically you can read Iribuya's guide:
