The third point is funny because I was learning Python and I think Javascript at the same time and at some point I crashed and stop learning both.
After 3 months I got back on the train and started to learn C++ and noticed how easy it is to learn C++ .... well because JS and Py already taught me a lot about programing in general line loops, vars, arrays and much more so C++ felt easy.
My Tip start html then a little bit of CSS (<10%) and then either Javascript or Python though I HIGHLY ADVISE JS due to its trueness to programing.
In Python you use for i in range(x): and that sounds way too english then actual programing.
