"成功と幸福の最大の敵は否定的な感情です。"

Simplified Meaning:

Having a lot of negative feelings like anger, sadness, or jealousy can stop people from doing well and feeling good in life. For example, if you are always angry at your job, you might not focus well, and you won't get things done properly. This can prevent you from getting that promotion you want. Similarly, if you're always sad or feeling down, you might not have the energy to try new things or meet new people, which can stop you from finding activities or friendships that make you happy. Think about someone who wants to start a business. If they let fear of failure rule over them, they might never take the first step, and they’ll miss out on the possibility of their business succeeding. To live a happy and successful life, it's important to deal with these bad emotions. We can do this by talking to friends or family, staying active and healthy, and trying to stay positive even when things are tough. By managing our emotions well, we give ourselves a better chance to achieve what we want and to enjoy life more.
