have contact with this language by hearing it on movies, tv shows and music. this will help you with your pronunciation skills and with your vocabulary
learn vocabulary and grammar at the same time
read kids books and translate what you don’t know. it might be hard at the beginning, but keep trying
speak to yourself will help you like crazy. I like to pretend that I’m acting or that someone is interviewing me hahah see the magic happens
READ AND WRITE. this is as important as speaking. It used to be so hard for me to write in English and I felt awful because I could actually speak very well. But my writing skills were just a lower level than my speaking level. Thankfully it’s getting better with practice.
try to study a little everyday. if you don’t have time to do so, watch a movie or something, but have this contact with the new language at least once a day
be persistent because the processes of learning a new language can really piss you off. sometimes you will understand nothing and that will drag you down. the difference is to keep pushing until it doesn’t bother you anymore!
