The mountain experience.

Goal and purpose - The peak.

Willpower - You can't give up midway, if not you gotta stay in the jungle.

Perseverance - You can stop and rest but you gotta keep walking.

Success - Satisfaction from reaching the top and taking in the breathtaking view.

Humility - When you're at the top, well you gotta come back down.

The times where we can learn from nature.
