I think the idea of writing down your first impressions for later referral is a very good one. Once you become immersed in the problem domain, you tend to quickly lose that very high-level view that you first had as an outsider.
I appreciate a new employee making suggestions as to how we can streamline processes, make documentation better, get up later and do the same amount of work.. don't underestimate how valuable it is to have a fresh pair of eyes.
I guess you can either have two bullet points and elaborate them quite a bit (because not everything is obvious to everyone) or just make more bullet points like the original. :)
I do disagree with your 'you can be an asshole %X more if you are getting results'. In fact I would consider being an asshole indicative of not getting results as it can alienate your co-workers (and boss!).
agreed. though also "3. don't be a jerk/asshole" should be up there, in order to not pollute the culture and make company less attractive/retentive for coworkers.
1. Get things done.
2. Make sure people know you're getting things done.
...and not necessarily in that order either. Being labeled "impractical" is the kiss of death in a startup.
Do those things, and most successful startups won't care about the other bullet points.
