Hi, to add on to the comments, beginner friendly websites such as Dr wealth and the Motley Fool also provide very easy to digest information regarding financial instruments and current market situations, which are an excellent way to buff up your knowledge regarding the financial markets and the important factors that affect their pricing, stability, investor confidence etc.

Personally, I include a website filtering service called Feedly(no affliation to Seedly) that basically allows me to choose the particular websites that I want to receive news from, and filter only business news, or certain keywords so I can get a quick fix of information when I wake up in the morning, and the headlines are organized into categories such as "business" "global general news" or "politics" to get me up to speed within 5 or 10 minutes. Very useful, and very convenient for a hectic schedule!
