Motivation
Most people who start a language soon give up. I'll teach you how not to be one of them.
Time
"I don't have the time" is the next big issue that I hear about from people struggling to learn a language. Let's utilize your time better!
Grammar
I'm anything but a grammar nazi. 🤣 But you'll still need a solid strategy to deal with grammar and know how not to become obsessed with it to the detriment of learning to actually speak the language.
