I found it very helpful to have your own rituals for the task you want to accomplish.
I create a spreadsheet with every startup before I start watching anything.
Then I start rating startups and comment on founders on my sheet while watching the videos.
I focus 100% on the first minute of any video, sometimes founders are so good they completely get my attention, sometimes I lose interest and just go back to my sheet commenting.
My sheet/notes are my starting point, if I’m bored I fix it there..I found out that I get bored when I hear a pitch that solves a problem for industries I’m not interested in.
I attended 4 online demo days, and every time my sheet gets improved.
I cannot watch these videos without a spreadsheet..and now my team asks me to send them the spreadsheet before every demo day.
I think YC should add a sheet for us to write our comments/ratings and decision.
The data from these sheets will be so helpful to understand how attendees perceive each pitch, how founders can improve it
