Either start your own company or find a company where you can be yourself and ship code and not have to worry about 33 lessons.
In this day and age we shouldn't have to worry about things like hairstyles and asking what turns out to be a stupid question.
If you're a superstar at shipping great software then nothing else matters - at least that's my experience in two billion dollar software companies.
Perhaps that's part of why they got to such a big scale.
Really good developers are priceless.
Anyone who is smart knows this. You just have to look at how much companies are willing to pay developers in signing bonuses and retention bonuses.
As a developer you should be aware of this.
Also, life is short.
Instead of choosing a company or line of work where you have to focus on things you don't want to focus on or change yourself -
pick an area you love and where people love you as you are.
Only idiot pointy haired managers would pick a clean-cut mediocre programmer over a superstar coder who doesn't shave.
And in my experience the superstars are nearly always not concerned with GTL (gym, tanning, and laundry).
If you're really good or make money for people (take Lady Gaga as an example) you can get away with anything. But most people or the people that that post is directed to aren't.
As a side note I always wondered why back in the day Bill Gates, when he was the richest man in the world (or near that) always wore a suit to business meetings. I mean you would think he would just do whatever he wanted to. But apparently he still had to answer to "someone" and felt it wasn't appropriate.
There was a time when there were Feudal Lords and now there aren't.
Similarly, we're moving away from a time of microserfs to hackers and coders who are free.
Love the downvotes - Guess people would rather take advice on how to be mediocre and miserable and do things you don't want to do than take control of their own destiny and find a company they love being at or start one themselves.
Also for many people there are a lot of factors that go into picking a career, location, amount of time spent with family, benefits etc. That limits options for a large number of people.
So while it's nice to "control your own destiny" it's also important to consider that to some people destiny is more than a career path, and that being mediocre doesn't mean being miserable. There are tons of people that are perfectly happy being mediocre.
No, we really aren't. Yes, it's easy to be independent if you have a marketable skillset, and it's a great time to launch a startup. That said, the vast majority of programmers are still employed by big organizations where these rules are very much in effect. They aren't directed at people who are working on their own; they're directed at the majority who are working in a corporate climate.
