Many have ruined their lives with this fear.
The fear of people getting advantage out of them.
Good leaders are very comfortable with giving more to people, than they take from them. Infact, they find their joy in it.
Thats also Eeman 101:
وَخَيْرُ النَّاسِ أَنْفَعُهُمْ لِلنَّاسِ
The best of people are those who are most beneficial to people.
