Seek assistance from those who are humble or just starting out. They will resonate with your enthusiasm and help you move forward, leading to a more dynamic situation.

棟橈,凶。
You might be trying to push through obstacles that can't be easily overcome. Ignoring advice because it doesn't align with your desires will lead to trouble.
