I’ve had a chance to briefly scan through some of the channels. Harvard Business Publishing is probably the most comprehensive. Tons of great videos to watch to your hearts’ content. Bear in mind, there needs to be a call to action on the part of the viewer, and don’t be spending all your time watching YouTube videos when you could be doing some trial & error. Putting pencil to paper and applying the strategies and tactics presented is what’s going to get you ahead of the game, not just by watching.
Utilize the videos as motivators to get moving. What are you waiting for?
