It is not about being able to know, touch and brag about a titan of which hypothetically beat someone else's Titan... In a world of invisible truth disguised in web of lies how can you tell if you are on the right track?
Listen to the Experts... Hum...Well you need to have the tools to understand what they say and use your own judgment to verify it because anyone can claim to be an expert in something they do not have much clue in it. It is just the way of the world...
Let's consider the psychological warfare that is out there which is all geared to acquire long term paying members and spread a cult of followers which is good for business. So what do the experts have to say about that?
Let start with discussing whats learning self defense is all about... You will need few hours of mental training to understand what you are learning and how to tackle it efficiently. It is about protecting your body and mind from irreversible harm. It is about learning to foresee bad things quickly before they happen and analyze the consequences.
Now it is show time. You obtain information pertinent to your plan to master hand-to-hand combat. Will it be a choreographed fight in a martial arts school? A score in a fighting sports record traced to a teacher? Dubious military past of combat stories of knife fighting, sword fighting or even gun battle?
You need much more than that. You need to understand the limits of the expertise! How long will it take, what will you achieve, how, and why... How many hours of training and how the whole program benefit your hand-to-hand- fighting skills to the point of giving you the tools to use your judgment wisely and decide when to engage and when not to and why, and the confidence that if you do engage in a physical confrontation.
You have done all the things that make sense to accomplish favorable success like leaving your home in the morning and fearlessly getting to your job or leisure place by walking, riding a bike or driving a car fearlessly.
There is you! Two arms, two legs a body and a brain...There is an unknown attacker... Same components different intents. Not much verbal communication but more of a body language and sound before you get surprised. Should you trust the verbal communications that are intended to control you by a threat or surprise anyway?
Now you need to set boundaries to tackle such a scenario. When can you afford waiting being passive and when can you not? The physics of such a scenario is the average human reaction time.
So know what to expect, try to figure out what is presented to you , what is suggested to you and how it relates to your overall goal of mastering hand-to-hand-combat and doing it quickly. What is quickly? How long did it take you to learn how to drive? How to ride a bike? For most attackers with hands on experience it did not take that long...
