Channeling:

Ancient China’s flood and how the Emperor solved it.
Identify your dry spots that you need some emotions (e.g., you are angry at work, so that motivate you to improve yourself, or find another job)
Build the channels before the flood comes
Channel your negative emotions to serve your positive goals

Examples:

• Channeling sadness to getting closer to Allah: The Prophet (SAW) after being rejected.
• Channeling need to humbling oneself to Allah and making Dua.
• Channeling anger to sadness

Infrastructures that you need:

• Dua
• Wisdom: Lessons learned
• Gratefulness
• Patience
• Drive: Failure is the mother of success
• Humor
• Reflections (e.g., poet get inspirations from emotional stimulus)
