Tomas, here's an important piece of information. Out in the cold cruel world, it's good to have skills, good to have knowledge but the most important thing for success, is getting along with people.
All kinds of people. Even people you wouldn't give a drink of water if they were dying of thirst.
I can't do it, so I've never been a "success".
You'll have to find out if you can or not, but someday you'll be sitting around reviewing,......you'll remember,... and say "yeah".
