Positivity
You may be more likely to trust and see the good in other people when you have a girlfriend, Dragun says. Knowing that she loves you and cares about you boosts your self-esteem, which makes you feel better about yourself. This is then reflected on your view of others in your life. According to Dragun, people who are in close, loving relationships tend to be more successful and are more satisfied in their careers. Achieving your goals may be easier and more enjoyable when you're on a team of two.
