I often think that listening practice is the most important skill - but depending on why you are learning, that could change. SRS is a good tactic for learning lots of content, but make sure you also learn lots of grammatical structures in with vocabulary cards. These are often most effective in the morning, when your brain is a bit more plastic. When I was learning Japanese I tried to book a lesson every single day, and that made my Japanese improve very very quickly. If you'd like to start speaking quickly, I am a very friendly and patient teacher, and available at the moment.
