> I guess the Old man saying the three team members lacking something is a "Dream Big" thing after all.
If you want to be successful, most of the time, the requirements are
1. Luck
2. Inherently blessed in that field
3. Knowledge Base
4. IQ as an adventurer (even you had an Einsten level IQ, it will not help you that much in fighting without an Adventurer's attribute)
5. Clear Goal.
In this case, the Goal of them was to become an adventurer, and live as an adventurer.
What the old man says must be, where do they want to go as an adventurer and what do they want to risk at being an adventurer.
Being an adventurer, the most successful and the role model after all are the A or S rank after all.
They didnt even become an A or S rank for being an adventure, right from the start, they had the aptitude, attitude, behavior, discipline and clear goals in mind on how to do it.
