Relying on others... you are making this decision yourself, right? If thats not the answer, doesn't fit in with other content of assignment, the answer would be trusting your instincts. Hope this helps!
Making a tough decision on one's own is something that requires a different type of values and skills so he could make the right decision independently. Independent decisions are the decisions that are made by without any influence but individuals own intellectual and thinking.
These values include knowing their boundaries so he can know what his limit, other value would be trusting his instincts and think the all factors through it, one can ask others opinion too but as it can influence him so he should consider as the last option.
