Just starting out.

Hello to all, I’m 24 years old and just starting out on selling for Amazon. Still in the verification process. Sounds like the long term goal is wholesale as I don’t have any ideas for private labeling. For someone just starting out would you recommend I begin with just book selling? I have about $40k to my name and am not in a rush to leave home. Or should I just get right into arbitrage and work my way up to wholesale? I’ve been doing research and see there are many obstacles to overcome such as restricted items. Any and all advice is appreciated. God bless you all!
