I went through some basic programming in school, by the 3rd week my brain went bye bye.. and I went in to it with an open mind.
First is, decide what you want to do:
You want to do coding/programming, is it something that you would enjoy or something you see that could make you money, but might be a slog ( Like me.. I despise programming now.. I'd last a week before I'd put a bullet in my head..)
Decide what you want to code/program.. there are alot of different ways and languages, Do you have a job in mind that you would like to apply for? if so then find out what the job wants in it qualifications, then learn that language.
As for finding the learning, some minor out lay of money may be needed, but not as much as a university degree. You can go to youtube and find some free stuff, but an actual class maybe needed. As above, decide on a language and then do research on what is offered/where. Find out your budget and what you can afford to spend.
Then when you learn the basics.. its going to be just doing it, repetition, going online and learning new things. It'll be an effort to do it, but if your motivated, you can do it!
