Your relationships will rarely be healthier than your self-esteem. If the time you spend alone is already enjoyable to some degree—that is, if you have a healthy internal monologue and generally feel good about yourself—then you will have a fairly high bar for the type of relationships you’ll enter. But if you’re unhappy with yourself, then you are more likely to put up with bad relationships because they may occasionally make you feel better than you do alone. If you want a great relationship, the first thing you want is to be comfortable with yourself.
