Your intuitive reaction to that question might be to say "Hmm, well this entire website is about the technicalities of tricks and having a full and accurate understanding of Tricking techniques and their consistent applications...so the answer is 'Very Important'."

Actually, it's not particularly important at all, usually. Or should I say, essential.
Now, just because I'm saying it's not important doesn't mean that it doesn't make you smarter, a better teacher, and generally more credible. But when it comes to the grand Tricking scheme of things, knowing even a book's worth of Tricking technical knowledge isn't necessarily going to help. Of course an understanding of some technical things is essential. But is the level of technical knowledge that is, say, present on this site, needed to become good at tricking? No.

If you look at most of the popular "favorite" trickers out there, who are capable of so many tricks and combos, you'll see most of them don't really know many deep technical details about their techniques. Of course, they're performing the deep technical details as they do tricks, but they don't have to know it to do it.
So just remember to have a balanced view of technical Tricking knowledge. It will most likely help you improve faster, yes. Is this necessary to improve? Not really.

So you may ask, why make a site like this then? Just because it's not essential doesn't mean that the knowledge isn't there. To illustrate, it's basically like any other form of science, physics, for instance. Every action you take is governed by the laws of physics. Do you have to know the theory and mathematics of the physics of the universe in order to live life? No. Do you have to study physics and understand the scientific principles behind life in order to live a meaningful live in this universe? No. But can you study physics to increase your understanding of the universe and perhaps benefit your life in certain areas? Yes.

More than that, there a whole lot of misconceptions in regards to Tricking techniques out there. Some people teach invalid concepts, or some people might just not understand what they're doing wrong, or why they can't land something. To that end, knowledge is always better than misinformation. So, this site hopes to cover as many bases as possible in regards to technical Tricking knowledge. I am a personal advocate of the proliferation and intake of knowledge in all aspects of life. Some people just aren't like that, and that's quite fine for the most part. So use this information however you see fit.
