Hi, my friends told me about SQL and that I could find a job if I apply to a looot of jobs. This is all new to me and I have no idea about all these languages. Could anyone give me like a beginner checklist of how to get into IT and where to start. And maybe somewhere to find all the tech lingo and such? Also maybe what should I also learn besides SQL that I should really know as well if I get into an SQL job? ALSO what I could learn in the future that could help my career in general as in moving up to bigger pay grades and such~ I was thinking of going into a data analyst job (if you have any good points about it to pursue or better job ideas please let me know) I heard a lot of people take free courses online and manage to find a job with that knowledge, is this possible and how do they manage to do so?

Thank you all so much in advance!!
