Of course, it’s not easy, if you’re just starting, heck, it’s not even easy after a break, but if you really want to you can do it. Choose a language you want to learn, get a good book, and start writing your own programs, no matter how samll they are for the beggining. With time you’ll discover more na dmore you’ll have to learn, but you need a starting point first. I am learning Java at the moment, and I hope it’s the right decision, at least according to the job ads here. You’ll need to braoden your horizon on topics like software engineering and so on, but I’d start with something small.
