There is nothing unscientific about anecdotes. The problem with anecdotes isn't that they are unscientific, it's that the scientific claims they allow you to make are very, very small. Anecdotally, I've found that Vitamin D3 helps me with motivation. That's a very small claim, but it's a scientific claim because I've experimented extensively with supplements to improve my motivation. However, "I've found that Vitamin D3 helps people with motivation" would not be a scientific claim, because I've only experimented on myself, and don't have enough evidence to extrapolate to the rest of humanity. Personal experimentation is a useful tool. It's how we know our personal preferences, fears, and hangups, which nobody else can tell us. Applying scientific process to it allows us to avoid some of our biases. We just have to be careful not to extrapolate our results to other people.
