Learning a new language is a TON of work. The process can be so overwhelming that you may not even know where to begin. But mastering another language can open up a lot of opportunities. You can communicate with more people, learn about other cultures, and be exposed to job opportunities that were previously unavailable. Learning a new language involves listening, speaking, reading, writing, sometimes even a new alphabet and writing format.
As a linguaphile, here are my tips!
Stay consistent with your study, and try to carve out some time every single day. Stick with it, and time will do most of the work for you!
Don't wait too long before starting to speak with people in your new language. It's normal to feel apprehensive about speaking when you're still a relative beginner. By speaking regularly, you'll quickly build confidence, and that will catapult your progress forward! Learn to appreciate mistakes, and push yourself to become more comfortable with making errors.
Read articles and check dictionaries (this method improves your vocabulary and helps you learn how a word is can be used in a sentence).
Listen to music, watch shows/television (it's best to listen to dialogues than songs, unless you want to learn to sing, because if you want to be able to talk, then it is important to learn how people talk). TV shows are a plus, it allows you not only to learn natural dialogues but you also get to learn more about cultures and how words are uterlized in different settings!
A little study each and every day is the best thing you can do for your learning. Consistency in language study is so, so important. It keeps everything fresh, prevents you from needing to do unnecessary review, and helps you continue to move forward.
