Except for Incred (no offense) I think all are good thoughts.
Keep in mind the most basic of questions...
1) What is the purpose of dating?
A: To find a spouse.
2). When is the right time to find a spouse?
A: When you are mature enough spiritually, emotionally and financially to support a wife and family.
So at 17 your concern should not so much be with finding a spouse, but with getting your ducks in a row for when the proper time comes.
God gave us a big beautiful world. Now is the time to learn, study, travel, and see all the wonders God has given us.
One of St. Don Bosco’s boys asked him, “Fr Bosco, what are we allowed to do in this world?” His simple reply...”Anything but sin”.
My advice to you would be stay close to the Sacraments, the holy Rosary, and your scapular. Learn, study, and suck every drop of the beautiful world that God has left for you and in His time, you will find the woman he wants you to be with...probably when and where you least expect it!
