If there is a situation you have to fight for self defense, it is recommended to drop your ego. Sometimes you might underestimate others and that can be dangerous.

When we learn martial art, we think what we are learning is the best. Of course, that's better. That's why, we are learning that. If you have an open mind, you can see some other martial arts are also better and effective.

Understanding the reality gives us a comparative advantage. Glad to know you do Judo. And you recommend MMA for self defense.

Yes, people learn martial arts for many reasons like the competition and fitness, as you said and I completely agree with that. Thank you so much @stimp1024 for your feedback. I really appreciate that!
