Hello All, Thank you so much for being there to have almost every question answered. I would to let you guys know of my misery and help me out. I have been working in an IT company for the many years now with absolutely no idea of what domain I am in. Its a normal IT job where I do not perform anything technical. And I think I am not going anywhere with this. Especially when I am almost 32 now. I know its late. Also I am not good at coding and guess I won't be able to learn coding. 'But', I do have some idea about SQL and at times & I think maybe I can try my hands at learning SQL. I also have a deep urge to learn Linux. The reason I mentioned SQL and LINUX is only because I think they wouldn't be too tricky(as much as JAVA, C, or any other programming language). Please let me know if I can go ahead with learning SQL and LINUX and if I do, What all roles can i apply for, in the future. I'd be grateful to you.
