First time selling, I'll try being online all day, every day, 24/7

My times are an hour before EST times, for example: 3 PM EST = 2 PM for me

I'll be as quick as I can always, please give honest reviews so I know what to fix and how I can be better as a seller.

through sports and school, I'm online for even when it says I'm not 12 hours throughout the day, and 16 hours on Saturday, Sunday, etc.
