Biblical Answer

Step 1: Understanding the concept of happiness

Happiness is often misunderstood as the highest goal in life. However, the Bible suggests that happiness is not just about feeling happy, but about living a life that is rich and joyful, and helpful to others. According to Proverbs 3:6, "Recognize God in all your ways, and he will direct you on right paths."

Step 2: The key to happiness - serving others

The key to happiness is not about achieving success for oneself, but about serving others. When we focus on serving others, we experience a happiness that is not self-centered, but rather a happiness that comes from giving. This is in line with what the Bible says in Matthew 20:26-28, "Whoever wants to become great among you must be your servant, and whoever wants to be first must be slave of all. For even the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many."

Step 3: Celebrating others' success

When others experience success, we should celebrate with them, even if it reflects negatively on us. This is a habit that can change everything, and it is in line with what the Bible says in 1 Corinthians 12:26, "If one part of the body suffers, every part suffers with it." By celebrating others' success, we demonstrate our love and support for them, and we also experience a sense of joy and fulfillment.

The final answer is: There is no final numerical answer to this question. The answer is a comprehensive and organized explanation of how to be happy for others' success.
