“Don’t learn multiple languages at the same time”

Ignored that. Suddently I understood why he said that. Mixed both languages. In holiday rechecked it and it was ok.

Sometimes mistakes can lead to good things. After relearning I understood it much better.

“Don’t learn things by head” was another one. Because that’s useless. If you want to learn a language, try to understand it.
I fully agree with that. I started that way too learning what x did what y did, ... But after a few I found out this was inutile. Since then, I only have problems with Git

Another one. At release of Swift, my code was written in Obj-C. But I would like to adopt Swift. This was in my first year of iOS development, if I can even call it development. I used these things called “Converters”. But 3/4 was wrong and caused bugs. But the Issues in swift could handle that for me. After some time one told me “Stop doing that. Try to write it yourself.”

One of the last ones: “Try to contribute to open source software, instead of creating your own version of it. You won’t reinvent the wheel right? This could also be usefull for other users.”

Next: “If something doesn’t work the first time, don’t give up. Create Backups” As I did that multiple times and simply deleted the source files. By once I had a problem no iOS project worked. Didn’t found why. I was about to delete my Mac. Because of Apple’s WWDR certificate. Since then I started Git. Git is a new way of living.

Reaching the end: “We are developers. Not designers. We can’t do both. If a client asks for another design because they don’t like the current one tell them to hire one” - Remebers me one of my previous rants about the PDF “design”

Last one: “Clients suck. They will always complain. They need a new function. They don’t need that... And after that they wont bill ya for that. Because they think it’s no work.”

Sorry, forgot this one: “Always add backdoors. Many times clients wont pay and resell it or reuse it. With backdoors you can prohibit that.”

I think these are all things I loved they said to me. Probably forgot some.
