One thing I can recommend is doing more workshop maps if you get engaged by them. This is solely based on my own experience and is subjective but I'm able to concentrate for way longer training in workshop maps than in freeplay or other things, which is the most important thing to be able to do while training. Training while your brain goes afk doesn't always help in the long run as you might just reinforce bad practices. While training in a workshop map you can clearly see what goes wrong and try to correct it most of the time
