Let us focus! Focus, people! I'm saying this to myself as well as to you. Everyone I talk to about what to do now while you're single says, "Focus on God."
This focus will manifest itself it different ways, be you male or be you female.
For the guys, you will build a career, gaining further education or training if you need it; get out of debt as much as possible; pursue hobbies and recreational interests; be involved in ministry or missions in some way (all Christians are called to share Christ and to serve the family of God and the wider world---whether in your current location and culture or as a missionary out of your "comfort zone"); and cultivate good relationships with family and friends, coworkers and supervisors, and leaders and peers in the church.
The women folk will do the same but in feminine ways rather than in masculine.
I know---that sounded really old-fashioned, as well as vague. Further explanation to come. My brain's shutting down for the evening. (Excuses, excuses, you say. I know. Forgive me.)
