If we are to believe some experts everything is the result of random accidents and not order. This of course fails to explain too many things. All biased views do.
Evolution is a long series of trial and error events, each with a learning curve or more attached. These potentials, unless activated and unlocked, will atrophy and die, never to be explored, never to have been given life.
It follows that any training will be similar in principle. Activate the latent or lose it.
The building of neural pathways requires necessity. In training we manufacture necessity in order to get practice at resolving it. This evokes the activity of the creative principle of Nature and The Universe to unlock creation from the subatomic levels, which then converges as intention or will; or as we say: ki. The more advanced being: aiki – skill or harmony in action.
Movement is a natural part of life. Lack of movement is a natural part of death.
There are individuals around who think that merely by thinking or watching movies they can still achieve the same results. But this is delusion. Or that by trying something only once, or twice, they can evaluate their potential as being somehow “different” from that of anyone else. Such outlooks lead to sad, self defeating outcomes where immense talent is wasted, thrown away and a gift disparaged.
How people can arrive at such conclusions is difficult to comprehend since the trail they leave proves them to be in error.
If you can walk or talk, you can do anything else that anyone else who can walk or talk can do, similarly or just as well. This has been tested and proven by those who did take up an active and regular programme of personal change, exercise or budo.
The question is not whether you can or not, but rather whether you are prepared to go through what it takes to do so!
