It's easier than ever in the current climate to feel overwhelmed with the amount of instructional material out there. If you're feeling overloaded with instructional content, or feeling like you aren't able to keep up with the community or your training partners--you aren't as behind as you might think! Here are some ideas to try and relax, and to understand that you'll progress at your own pace. 

One of the best ways to improve at BJJ is to find a process of improvement that works for you, and to learn to love the process more than the specific outcomes of your rolling sessions. Doing this will keep BJJ fresh and enjoyable for you, and the low moments won't feel as low. Be patient and kind to yourself, and have fun!
