In a relationship, it is not enough that you work on yourself.
Self-development is very important. The problem is that personal growth rarely includes working on a relationship.
Many people are surprised. They are working on themselves, but their relationship is not developing. Sometimes is even getting worse; they become distant from their partner.
If you want to develop your relationship, you need to work on your relationship, improve your communication. You need to create a vision as a couple. You need to work on becoming a happy, loving, fun to be around, fulfilled, and successful couple!
In a relationship, it is not enough just that you work on yourself. In a relationship, you need to work also on your relationship!
