I'm sick of finishing my half of trades and having to be like 'oh ok, it's cool you won't finish your half'

I'll only do trades with close friends OR if you swear to finish your half first.
I don't have a lot of free time for drawing anymore, so I don't want to waste anymore of my time.

ALSO for commissioners, I will no longer do a free 'planning' sketch before payment.

I've had my sketches stolen before payment, so people would say 'oh nvm I don't want it anymore' so they don't have to pay.

From now on, I will require payment upfront. I did it as a way to show people I will get their art done, but I can't do that anymore.

Sorry to the majority of people who are decent people, but I'm sick of getting used.
