Light, (Raito) Yagami from Anime / manga Death Note is a very interesting character and that's why many people want to look like him. While it is impossible to be exactly like him, you could take him as a role model and try to copy some of his characteristics.
Steps
Step 1. Don't be flashy
Light's main characteristic is that it is almost always calm and controlled. Choose a classic haircut. Try to have a calm expression, neither too happy nor too angry. Also try to be fit and maintain a body mass index (BMI) between 16.7 and 17.0. It is essential not to drop below 16.7 or exceed 17.0 points as otherwise you will not be quite as athletic as Light.
Step 2. Model your character
You will need to be able to consistently make the wisest decision (or rather, the decision that will get you the desired result). Leave nothing to chance and try to be always in control (but Not show it too. Bragging or proving to be the leader is not a good idea because it attracts attention.) If you want to be like KIRA, on the other hand, you have to be able to cheat. Accustomed to performing acts that are morally questionable in order to achieve the "greater good". Also, don't feel guilty about your actions, even if it's about getting your enemies out of the way, they were basically just obstacles. On the contrary, if you want to be Light you will have to behave in the opposite way. Never do anything that is morally wrong, for any reason. Take care of the people around you, even if you don't like them.
Step 3. Have courage
While this may seem like a contradiction to step number two, you must always have courage. When you have the choice, always opt for the winning solution. Plus, never accept defeat. If you lose, at least try to get to a tie. Obviously, do not show that you are frustrated or angry but be calm and serene. Seek rematch later (in secret, of course, or in a way that no one can trace you, for example by creating an alibi. If you want to be just Light, express your pride openly, never manipulate or steal, and defend your honor., even at the cost of using force).
Step 4. Be smart
Do you remember how Light got a perfect score on the To-Oh entrance exams? What about the plans he devised that all went so well in the end? Your reasoning, your knowledge and your judgment must be at peak condition and you must be able to know yourself and those around you extremely well. Predict the actions of others both by thinking about real and hypothetical situations. Improve your math skills and have more charisma. By having a large number of skills at your disposal you will be a better person. It also tries to train the mind. Try to solve puzzles and learn to play chess (Light is also a good hacker).
Step 5. Use a little madness
Light has his moments of madness (or rather, it's KIRA who has them, but the point doesn't change anyway). Learn to smile scary. Plus he learns to grin and laugh under his breath without look like a fool. Admittedly, most people who try to make a wicked laugh seem stupid, but not Light. Because it has charisma. However, if you want to be just like Light and not KIRA, learn how to make your eyes shine. This way you will have more charisma but in a different way (and this has nothing to do with insanity, rather with persuasion. It is better to highlight this aspect to understand the difference between Light + KIRA and only Light.)
Step 6. Always have a plan
Light plans his every move in detail, making sure there are never any forgotten details in his plans. It's always a good idea to have a plan B too, if plan A doesn't work.
Step 7. Be confident but cautious
Do you remember all the precautions Light took to find out if someone had broken into his room? Even before finding the Death Note, Light always placed the piece of paper in the door and the lead wire above it. And also the trick of the handle. He certainly is a genius, even if he doesn't seem like one. Always remember these types of precautions, for any situation. This will show that you are ready for any eventuality.
Step 8. Be independent
Light depends on someone only when he knows he can manipulate this person enough to trust. We all make mistakes but Light can't afford even one.
Step 9. Try to be quiet and reserved but also have the social skills to join any group
Try to be fairly approachable when around people and bring interesting insights into the conversation. Finally, try above all to think before you speak or act.
Advice
- Never act fully like KIRA, unless you want to go to jail!
- Light is a hacker who wants to increase his knowledge, to build and not to destroy. Always remember that.
Warnings
- Don't hurt others for no reason or you will become the villain, not the hero.
- Light lives in a fictional world that is not like ours. Try to be more like Light and not like KIRA.
