Watching someone ride a bike has never taught anybody balance.

Some things cannot be transferred by watching, because the knowledge is not information. Balance gets built by your body making a thousand tiny corrections it can only learn by making them wrong first. Watching gives you the shape of the thing, which feels like progress and is not. That gap is why people can describe a skill perfectly and still not have it.

Look at whatever you have been researching instead of starting. Find the smallest real version of it, the equivalent of getting on the bike in an empty lot, and do that version this week. Wobbling counts as learning.
