For me, a streak is how a person values how something always is. So, it’s more likely to continue that way.
Newton’s First Law says an object at a state is to say in that state. This is basically what a streak means.
Therefore, for example, some own easy habits such as. Bushing your teeth before sleep. This habit could be considered a streak to my own psychology in saying that. Your own health is important.
Streaks are such powerful things. If a person is good at something and people keep telling the person that they are good at something, that’s called a streak and they will just keep getting better and better.
