Alright, so if you are hungry, can you trust MacDonald's and KFC to provide you nourishment every time that you need it? Or would you rather go and look for food of your own, perhaps even gathering ingredients of your own and cooking it yourself, using your own ideas?

Following signals is like blindly eating someone else's shit that they are trying to tell you is good for you. Try to learn about what signals are and how to recognize trends rather than just trusting these people who want to make money using your money.
