Order cancelled after a long time(How to recover from it)

[jd_fit]

Hello everyone,
After 4-5 months, I got a order cancelled today which was 70 percent of my fault and on top of that it was a Fiverr’s choice order.
I suspect the impressions and clicks will go down after this but I want to ask the experienced sellers here that how to recover from this or how to get up from this hit or cancellation effect.
Will this affect me a lot ?
What should I be careful about ?
Regards,
JD
