Self-reliant describes someone who strongly prefers to handle things on their own rather than depend on other people. People high in this trait may avoid asking for help, feel uncomfortable accepting support, or believe that relying on others makes things less dependable. They often feel most capable when responsibility stays in their own hands.

At its best, this trait can show up as competence, independence, toughness, and the ability to stay capable under pressure. At its extreme, it can become isolation, refusal of useful support, or taking on too much alone when collaboration would make life easier.

A recognizable fictional example is Jason Bourne from The Bourne Identity. He represents someone who operates independently, relies on his own skills under pressure, and rarely trusts other people or institutions to handle things for him.
