There are many ways for someone to be admirable. He or she could be someone who leads by modeling first, so his or her authenticity and transparency are characteristics that are attractive to others. They could have a vast knowledge of a topic that other people wish they knew more about. They could be generous with their time. They could have the ability to hope during even the toughest and darkest of times. They could teach very well. They could make things happen just by their sheer influence. They could give the most sensible and practical advice and don't offer an opinion that's unsolicited. They generally make it hard for you to imagine life without them.
