Caution: you don't want to get into postmodernism yet. Not at least before you find some firm footing in basics of philosophy. Reading Foucault has become a fancy, but you can wait for a while.
It is always good to begin philosophy with crash courses that can give you an overview of happenings in philosophy. That way, you might get interested in a particular branch of philosophy and take your interest forward from there. For example, philosophy of mind is an exciting field to explore. However, I'll leave that to you. Philosophy is a practice as well. So, pay attention, and you might benefit from taking notes. Do not rush. Take your time.
This course is an introduction to philosophy, and it starts with the fundamental question: What is philosophy? So, you might be interested in starting with this course before moving on to higher terrains.
Suppose you are particularly interested in logic, reasoning, and arguments. It does you well if you can start and finish off these four courses. Refer back to the crash course playlist to get an idea of logic and argumentation in philosophy.
This course is the best course you might come across in your life. Justice by Michael Sanders is an epic course. Once again, to understand what justice is, you might want to refer to the crash course and some of the resources I am providing below under the name 'Websites for Philosophy.' He has written a book by the same name.
Websites for Philosophy
https://iep.utm.edu/ (Using this website to know about a philosopher or a concept is an excellent way to begin)
https://plato.stanford.edu/ (Very advanced. Hold on to it. Nevertheless an indispensable resource to have).
Wikipedia is fine but does not just rely on that alone.
People to Avoid
These are dangerous philosophers (I'm not sure if they are philosophers at all) - potent enough to brainwash anyone.
These youtube channels you can refer to if you are interested in the content. Interestingly, most of these channels provide sources below. It is always a good idea to read the material provided (Of course, not everything for now, but something that interests you).
Avoid anything by 'School of Life.' It is the worst channel I have come across
