Okay, in answer to your question, my background is mainly in
Network/System Administration. Starting on Windows systems, and then
moving into Unix/Linux systems after that. I've played around a bit with
VB and C++. I've never had any problems with syntax, it's been the
thought process behind it that's been an issue. To give an example, I've
never been good with spoken languages. I can learn the syntax, but I
can't "think" in that language, so I've always struggled. By that I mean,
when (for example) someone is talking with another person in Spanish, do
those people hear English, or do they hear Spanish and translate it to
English in their heads.
I hope that's a clearer example of what I'm looking for.
Thanks,
Tom
