It's a way of saying that you have a particular personality or habit that you can't change. It often implies that you're comfortable with who you are, even if others may not understand.
Here are some examples of how it can be used:
* "Soy sólo ese tipo de persona que siempre está sonriendo." (I'm just that kind of person who is always smiling.)
* "Soy sólo ese tipo de persona que necesita estar ocupada todo el tiempo." (I'm just that kind of person who needs to be busy all the time.)
* "Soy sólo ese tipo de persona que no puede decir que no." (I'm just that kind of person who can't say no.)
The phrase "Soy sólo ese tipo de persona" is often used to explain your actions or behavior, especially if it's unusual or unexpected. It's a way of saying that you're being true to yourself, even if it means going against the grain.
