All listed not just by OP but for others as well is not a mistake totally if newbies did those since they are in the stage of learning.
It's totally a mistake if it's done by an experienced bitcoin user or a user that already in bitcoin world for months but still can't understand even just the basics.
6. Waste time on faucets (we all did)
7. Collect dust and pay high fees on it
We don't need to pay fees back then when using faucet as payment processors pays for it such as Faucetbox. And upon receiving on the web wallet no need also to pay higher fees because they covered it. Also in my case, if I didn't waste time on faucets, I will not reached my status today.
