"Errors? Won't happen to me!"

One of my first jobs was to finish and maintain a program, that was made by a guy who had a real genius image among others. Years later, people said "oh him, that smart guy."

I never met him, but that's what i heard.

However, he was not only smart, but it seems he was also very confident. That's what i deduct from his code.

He didn't use catch-blocks. They were all empty. Not even logged.

If errors appeared , it was not possible to see what happened and where and why. The program would continue it's execution and if following steps could not work, because there had been an unnoticed exception, it would just throw another unnoticed exception and at some point, end in an undefined state.

On my first dev job ever, I got sent to the client's office after studying CSS on my own for 2 weeks.
Client: "So, you're the great expert your manager told me about?"

Well fuck me sideways with a rusty lamppost.
Got assigned to a project at work, kind of a biggie, my first actual large project. Been working there since last year, done a lot of research in my spare time and felt like I deserved it or something.

But then...

A few weeks ago I posted a rant about a fuckwit that can't even type 'ssh' in a terminal and doesn't know how a basic database system works.

Guess what.

Yeah.

Exactly that happened.

Because of his overconfidence and big mouth he got assigned to the project as well.
He planned a pitch. Stole my words.

He hasn't proven himself in any way and always needs help. Always. And I don't have a problem with people asking for help, I actually tell people not to be afraid to ask if they don't know something.

But I do have a problem with people laying back at work and asking 7 different people how to open a terminal.

Why does this happen? Just why?

Overconfidence​ is striking again. Some companies are really begging for it... Found this cup in the kitchen of a client. And it is the slogan of an external contractor. It says: this network is unavailable for hackers. I think this is worth at least a triple facepalm

Oh,I have learned a lot, I would not say from programming but from the career as a whole

Never get peer pressured
Always show empathy
If in a leading position, taking care of people is your top priority
Overconfidence will destroy a lot of good work
People by definition will always remember your mistakes
Never get over involved in the company you are working for, it's just a job
Your health is more than important
Nobody knows everything
Always be humble
There is a lot of bullshitters out there
Success is relative
Competition is high and there is always someone with better skill set, so you will suffer if you don't accept that
