Both. as an aspiring entrepreneur, I learned how important is your network, it's important to have enough connections in order to succeed, you still need capital to learn how these successful people operate. It's either you do courses or hire someone as a coach. These coaches learn strategic ways to succeed, they spent enough time and energy learning it through experience.
Networking is really important in many professions but unless you plan to become a money manager I do not see this as being as important as it may seems at first glance, after all you do not really need anyone to teach you how to trade when you can learn this on your own and you can use your capital to trade the markets and obtain profits, so in that instance networking is not going to bring you any benefit and you will just waste your time when you could be dedicating that time to improve your craft.
