John Dugan, aka the Resale Rabbit has hit the road hard. He has experienced America and spent a lot of windshield time and takes you along with him on his Youtube channel: Resale Rabbit where he gives great advice given really cheap (free), so check him out.
Johns solid advice:
1- Give up control! Use FBA, use a repricer, get local help
2- Compete with yourself not others- Others success is their success, look inward rather than outward
