Newbie investor

I am starting to invest in stocks and more. I understand that you can’t really time the market, so my question is - Any one source where I can get the basics of what’s what for beginners. - How do you decide on which company to invest? Is it based on the news, investment knowledge sites like motley fool, investment books etc. Or combination of all such things. - What are some of the resources you use? Like websites to check out for upto date info, books to read for making wise investment, Tools to give an edge etc. - What is the best investment tool for serious investment like Fidelity, Charles Schwab etc. Would really appreciate some advice from all you experts out there.
