1. They can face with their fears
They are not fearless, they are just brave enought to face them.
2. They inspire others
Their actions inpire others who are afraid to take a step.
3. They fight against difficulties
While some give up as soon as they come across any problems, brave people fight it.
4. They say how they feel
5. They say no to the things that they don't want to do
I think that's the most important point. Lots of people are afraid to say no. They go to parties, meet with friedns, and even accept dating with someone that they don't want to. Keep in mind that saying "no" to the things that you don't want to do is not rude. There is nothing to afraid.
