Death Note shows us that overconfidence can destroy even the most perfect plan
The main hero is an exceptional student: he excels in every subject, receives the highest grades, sets records in school, and spends his free time studying. He’s brilliant at almost everything, but when the time comes to fulfil his plan, his overconfidence makes him reckless.
This is something that many traders face every day. They prepare a perfect plan, but when they start trading, their pride takes over and makes them strive away from the initial strategy.
What you can learn from Death Note is that you should never let your pride drive you away from your plan, or everything you worked to build may come crashing down.
One Punch Man teaches us that practice makes perfect
Sometimes the best thing you can do with your life is something nobody else does. The main hero of this anime is a simple man who gets sick of his boring life and decides to quit his office job to become a hero. Not only does he realize his dream, but he becomes the strongest hero alive in the process, able to defeat any enemy with just one punch.
But he doesn’t have any superpowers. When he’s asked how he became so powerful, he simply answers “100 push-ups, 100 sit-ups, 100 squats, and a 10km run every single day.” There’s no special secret, no radioactive spiders, no meteors, just a regular everyday routine - that’s what makes you successful.
