I’ve only been programming since 1977, and have learned several computer languages over the [task lists]. 
The more I study Julia, to begin writing code in it, the more and more complex (meaning capability!) it gets! Wow. And I’m only in the “See Spot Run” stage! Yes, I have written many simple and quite complex programs over the ages… My favorite language is “C” esp with embedded equipment and Arduino’s and such, but I also positively reveled in the ZIM DBMS language which used relational calculus (but it’s dead now )
rather than (difficult) relational algebra like SQL and it’s ilk. First DBMS was dBase back in the late 70’s if anyone remembers that.
Read a couple Julia books, one a primer and the other a “high performance in Julia” topic.
Welcome!
Thanks!
Been there myself. I was weaned on FORTRAN IV. 
Julia may seem complex, but I never found programming so easy in other languages (C, Fortran, Ada, Pascal, C++, Matlab, …). I’m sure you will have a blast, and there is nothing like this forum to help you if and when you happen to feel overwhelmed.
It’s like building a skyscraper. The Julia primitives all look so simple and direct, Take this command, place it right there, and voila. You’ve just added a girder and you feel good and satisfied. That is, until you look down and see the 107 floors that you’re standing on to get this far.
That is the image I see when trying to construct an algorithm in Julia and am still on the very first line of the program

Don’t hesitate to ask questions here on the forum. Of course it’s easiest for us to help with specific questions with code examples.
