I've never made a deck before, and I'm not sure if this is what it's supposed to be like. I've read through lots of advice (ex. from Venture Hacks), but still feel unsure.

The main thing is that I feel like I'm making a bunch of claims, but not supporting them with arguments and evidence. However, if I try to provide arguments/evidence, it'll get too wordy, and all the advice I read says to keep it really short.

Am I not providing enough evidence? Other thoughts?
