This is just a discussion.
These are not my words.
Your enemy is yourself. How to defeat him or her? You should know yourself, research, and initiate the plans. Suppose that your name is “Jack.” Jack is very lazy. Jack evaluated that Jack makes Jack lazy. Then, he was thinking for the whole day why Jack makes Jack lazy. Jack figured out that his lack of sleeping makes Jack lazy. For that reason, Jack researched a variety of books which help his sleeping. After a full week study, Jack learned to sleep better. Finally, Jack defeated Jack. What about an woman? Lily likes sex. Lily detected that Lily makes Lily want to sex a lot. Then, she was meditating for the whole day why Lily makes Lily want to sex. Lily figured out that Lily makes her want to sex because she wants to feel popular among guys. Lily decided to go to a recovery group and fixed the problem. Eventually, Lily is having a good time without sex.
