eing able to open your phone to get a quick coding session in is extremely valuable. I whip these apps out while waiting in a long line, at a doctor's office, or when I'm just sitting around leisurely. It beats opening social media if you're on a detox like me. Anyway, always be coding!
Free is always key when you are first starting. Don't go buy hundreds of courses just to hoard them. Start with free courses and complete them. If you are still interesting, invest in your learning from there but always start with free.
