A lot of us know a thing or two about relationships. Some are good and others are downright awful. The differentiating factor is not usually about the differences but rather the level of presence that one gives to the relationship. The more wholeheartedly present you are in it, the higher likelihood the relationship is going to be good, ceteris paribus of course. Being with someone who only gives 50% when you are maxing it out is only going to cause you disappointments and eventually lead to heartbreak. Regardless if it is work or personal ones, commit to only get involve with those who are fully present. That said, you too.
