Look away. Don't meet their eyes, don't stare at their face. Just don't.
2. Don't think about them. Rid them from your mind, think of other 'better' things
3. Don't look at them when they are happy. When their eyes are shining and their smile is large. Don't let it make your heart sped up. Refuse.
4. When they are nice, remember that they are not doing it for you. They are polite. That is all.
5. When they talk to people like they talk to you, or they flirt with them. Don't be jealous. They are not yours.
6. You are not right for them. Remember that. Above everything else, you do not deserve such a imperfect masterpiece.
7. Give yourself space. No matter how much you want to be with them. You can't. You need to stop. Make sure you aren't attached. (You are though, you know that. Ignore it)
8. Distract yourself. Whenever you start thinking about doing something. Read a book. Get lost in the pages. (Realise the thought come back after the book is done. Accept that. Start another book. Drink lots of tea.)
9. Convince yourself that you don't care. They aren't that important. Only a friend. Only a peer. Nothing more.
10. You don't care, you can't. There is absolutely nothing that can make you care about them. (But then they smile)
11. Know that it will pass. (It won't)
12. Make sure to never be in same room alone. Your mind will wander, hopes will grow.
13. Make a list. Why are you not compatible what do you hate about them. (The answer: not a lot. Everything you don't like is manageable)
14: Quit. It's hopeless
