Horace said “Rule your mind, or it will rule you”. You have the ability to train your mind and control your thoughts so your mind obeys you, not the other way around.
- What is the meaning of rule your mind or it will rule you? @ Quora
Excerpt: Simply put, it means the mind is your slave and not the other way round. Imagine you are walking a dog on a leash. Here, you are in control of the dog and the dog obeys your instruction. However, in a different scenario your dog is running here and there dragging you along with it. The dog has to be trained to see you as the master then. Similarly, you should train your mind to obey you or it will drag you around.
