If someone wanted to improve their thinking, why should they study philosophy and not just learn logic and critical thinking?

I've never studied philosophy (e.g. read the works of Aristotle, Plato, Kant, Descartes etc. except for a few passages or quotes online) but I have read and studied a lot of intro to logic and critical thinking textbooks

If someone wanted to improve their thinking, why should they study philosophy and not just learn logic and critical thinking? 

PS: I think the reason I've hesitated reading the works of philosophers in the past is that I'm put off by old styles of language e.g. Shakespeare, however, if the works of these philosophers were written or updated into modern English I'd be more inclined

EDIT: I would be most interested in a branch of philosophy that specifically focuses on how ought one think/reason. That may simply be formal and informal logic, potentially some epistemology too. I'm interested in both the theory and practice. I'm not interested in ethics, politics, aesthetics, axiology, etc.

I mean the first thing that comes to mind is that logic and critical thinking *are* philosophy. But also, if you’re not interested in the earlier western philosophers you mentioned, does that preclude you from reading more modern philosophers? Not all philosophy is from that era! Try something new and readable to you. Engaging with other ideas is beneficial to your own thinking.
