Having someone goal-oriented, with superb planning skills can help you to break down your goals into small easy to reach accomplishments. They can work with you to figure out where your next move should be and help you with making decisions.
This is the type of person who can help you take a step back and view situations objectively, and can help you gain a whole new perspective to problem-solving and overcoming challenges.
Someone that has overcome adversity, has gone through life-changing events, can help you build empathy. They can show you what life is like for the other person and help you emotionally connect with others.
