A large portion of the thoughts and feelings you have are not yours, rather you pick them up from others. This may seem entirely shocking and untrue, but you can do an experiment to fact check this for yourself. Go for a hike alone on an uncrowded trail and take note of the number of thoughts you have. After you have been hiking for an hour or so, you’ll notice your mind is very still and that you don’t have many thoughts. Next go to a mall or someplace crowded and walk around for a while and observe how many thoughts are running through your mind. In a crowded place you’ll notice your mind becomes very loud and full of thoughts.
It’s helpful to be aware of this phenomenon because if you’re around an angry person, you’ll notice that you’ll begin to have angry thoughts. If you’re around someone who is worried about money, you’ll be worried about money. If you spend a lot of time with someone who is depressed, you’ll feel tired or hopeless when you’re around them. When you realize that a lot of the things that you think and feel aren’t coming from you, you can be an “educated consumer” and not spend as much time with people or in places where you pick up crappy thoughts and feelings. You can also learn to not act on the emotions that you pick up externally that aren’t yours.
