If you have trouble sticking with one language long enough to get good at it, it might not be as bad as it seems. Learning a language until mastery takes a long time–exactly how long depends on the language and other factors–and this requires commitment. The commitment usually isn’t sufficient in the beginning. Thus, it’s easy to find yourself changing languages frequently. This month you’re studying Italian, the next Russian, and the next Japanese.
There are unusual individuals who can start a long enterprise from scratch and remain committed from day one, for as long as it takes. Others have a motivation so strong that the commitment comes easily. Yet others have outside support (from a school or parent, for example). But most of us don’t fit these descriptions. What do we do?
If there’s a language you really want to learn but you are having trouble being committed to it, my advice is to dabble in it. Then dabble in other languages. After that, dabble in this language again, and try to stick with it longer. Then dabble in something else. Always return to this language. After a few rounds, either the commitment will come or your interest in it will disappear. Once the commitment finally arrives, make this language a priority and a habit. Make studying it even a little everyday a part of your life, like eating or sleeping.
Each time you return to this one language, you’ll no doubt want to review what you studied before and then continue the same textbook, course, or app. By all means do that, but also study from a different course or app at the same time. Why? Because you need to make each round of study a new experience rather than trying to repeat an old one. Mere review is demotivating, but experiencing the language in a new way is invigorating. Furthermore, you might learn that you don’t like your previous course or app as much as you thought you did.
It is my hope that your dabbling in various languages will lead you to fall in love with at least one of them, and then you’ll be on your way toward commitment. Even with a strong interest in a certain language, it might take several rounds of dabbling in it before you find the strength to maintain a habit and persevere until mastery.
