What does Gung fu mean to you? Maybe you misunderstand me, skilled hard work is just that. That’s two hard working people. The hard working person you are today, and the one you aspire to be tomorrow. This is what makes a skilled practitioner, whether they be dishwasher or martial artist.
That's true. Gongfu does refer to skill achieve through time and hard work.
However, I hope it's obvious that being skilled at one thing does not equate to being skilled at something else, which may not be what you were implying.
For instance, being skilled at mopping the floor is not a legit vehicle to learn Taijiquan, nor is it a useful replacement for the form or the traditional curriculum that has been passed down for hundreds of years.
Had that been the case, there would have been no need for tradition. The whole point of tradition is to stand on the shoulders of giants. So... tossing that giant out the window is not exactly a good starting point.
Part of the issue with the conversation in the thread has also been a lack of definition on what "Internal" even means. Lack of consensus in definitions is a huge root cause of disagreements on this subject.
Personally, my bias (as it relates to my lineage) use the term "Internal" most frequently when it comes to a higher ratio of body-core to limb connection.
For example, if you think of a shitty Wing Chun punch, it's very localized, just arm power. That... is what my social circle would call "External".
By this definition, "External" does not mean "brute force". It just means... the ratio heavily favors the extremities of the body.
And "Internal" relates to a lot of connection that more heavily favors the torso: Dantian, Kua, Chest, Spine, Ribs, etc...
However, when I say that an art should be both Internal and External, by this definition (and I am not saying this is the one and only definition), all I really mean is if you have a good body core engine... the extremities shouldn't be limp and floppy. A lot of "External" Chinese martial arts have a lot of fancy, cool hand shapes. Their hands are very hard; they're weapons.
And that is a side I think a lot of Taiji has lost: leg foundation, structure, frame, "hand gongfu", hardness, etc... Although... I don't think they have much of the torso stuff (Shen Fa/Body Method) either.
