Students of psychology are educated to consider in their treatment approaches people's personality traits. There is a multitude of clinically researched and empirically supported tests and measures, but one of the best tests I've found for understanding your own tendencies is the Enneagram.
The Enneagram will help you understand what motivates you, how you think, and how you love others. It provides common insights into the reasons why you do what you do and how your actions affect others.
Because I'm a visual person, I like to use imagery to further expound ideas and concepts.
There's a saying, "Still waters run deep." To correlate some personality styles consider the following analogy:
Some personalities types are like lakes. They appear calm and collected and can feed many streams. They remain calm until a strong wind churns and turns the surface and the waters are tossed and turned creating chaos until the winds stop blowing. These waters are greatly affected by the environment around them.
Some personalities seems calm on top, but there's a raging river running just below the surface. These waters often are where the lake and the streams connect. The streams gain momentum as they rush down the mountain top. They cut a path through the environment rushing toward a final destination only to learn that the destination is a lake, but you don't want to be a boring lake. So you look for another outlet seeking the rush again.
Maybe you have settled in an outlet, a pool of water alongside the stream. Close enough to feel the current, but clinging to the bank for a sense of calm security. Fearful that at any moment the current could carry you away into a place of uncertainty.
Other pools of water find no refreshment from the stream nearby. Nothing stimulates them so they turn stagnant, collecting toxins, trash, and debris.
Maybe you're more like a salmon trying to swim up stream against the river current and can't even relate with the water that sustains you?

"If I could speak all the languages of earth and of angels, but didn’t love others,
I would only be a noisy gong or a clanging cymbal."
