Repetition and consistency is the key. This is a perishable skill set, you have to stay sharp and consistent with it. There will be times where you will feel bored, you may plateau, you may even want to quit (or life shit will come up forcing you to take a break). Don't over think it, just have fun and challenge yourself. Even if someone starts after you, and they seem to excel quicker, don't let that discourage you (BJ Penn got a black belt in 4 years.... It took me 16).
Also eat well, listen to your body (understand the difference between sore and injured though), rest where you can, never sit out from training (unless you're legit injured).. If you're tired, play defense, survive and escape. You WILL get tapped A LOT, the key is to learn from the process of what got you into the bad positions.. Don't just shell up and not move. Ask questions and pay attention to the finer details..... And drill, drill, drill
I'll simplify the process..... Create angles and transitions, remember that it is important to have good posture, base, and position rather than ill advised submission attempts.... Take whatever joint in the body and hyperextend it into it's opposite natural position... Cut off blood to the brain via carotid artery choke, or cut off air via a tracheal choke.... There you have it LOL
