Where to start and where to go from there?

Call me a cheater 8)
4 year BS EE degree, design engineer for a living. Coding experience from classes, projects, reading other programs, starting with BASIC in high school.
Arduino IDE seems like more capable version of BASIC to me at this point, but I think classes in FORTRAN, Assembly language, PASCAL, other classes I don't even remember taking now, programmingTRS-80s and Commodore 64s, and reading other programs here in the forum for quite a while now, have all merged to help in my programming.
Then asking questions here from the real programmers for details that weren't clear how to get to.
