I just don't get the need to figure out a system that represents the true way of taking notes. Everybody is different: different in skills, needs and working styles. Some want a diary, others a 2nd brain. It doesn't matter which system you pick, the result will be: it fits somewhere between 50% and 90%.

To take clothes as analogy: when you buy a shirt off-the-shelf, you can (usually) choose between XXS to XXL. Let's assume you want to wear the shirt for the rest of your life, wouldn't the natural conclusion be: a tailor-made shirt?

The real solution is to take one note taking system as starting point and adapt it to your needs. There is no shortcut, it will take a while till you've figured out what your needs are and how you can adapt the system you chose.
