maybe it's waking up every morning and reading articles called:
design is not a. it's b. designers should c. designers should not d. designers should study e. designers should use f, not g. hi i'm a designer and i work at unicorn and we did h, you should do h too. why your job title is not x, and it's actually y. go to this z conference to learn more. wait, nevermind, i fixed my design flow with a moleskine and this one weird trick.
Thats an excellent point.
Every day we're told by other designers were doing something wrong. That we aren't a real designer unless we do X. Etc.
It leaves designers feeling confused or constantly stressed wondering if they are behind/out of style so to speak.
I think this shit is absolutely critical, we get way too caught up worrying about the latest ideas, technologies, blog posts, newsletters etc., when we should we pouring the majority of our energy and attention into doing the work.
If I can crowbar a metaphor in here; done is better than perfect. Sod all the noise, just turn up and make things.
If I actually took all of these articles as gospel I would actually never get anything done; I'd be too busy researching, going to talks / meetups, doing side projects, doing courses, testing out new services, trying the latest plugins, contributing to projects on GitHub, listening to podcasts, doing bug reports for my favourite UI app, putting stuff up on Behance, writing posts on Medium and being constantly available on multiple Slack Channels.
Navel gazing is easier than doing the work.
Because external forces are relentlessly degrading the original design in order to fulfill the individual stakeholders' individual vision.
Whether that's another article telling me to use or not to use X pattern, another client telling me he wants X item bigger or bolder, a specific users' use of the design in an unexpected way, or the designers external obsession with the font proxima nova, it all comes down to competing forces breaking down an original design into pieces that no longer can collectively be referred to as "good design".
There was an excellent article about this about some design decisions Facebook made. I believe it was written by a designer at Facebook but cannot find it right now. I also believe it may have been related to LGBT/identity.
