You know, dating is not the key to happiness. I am a 18 year old guy and I have been dating for years, but after doing a reflection on myself, I could have excelled well if I haven't dated. Don't get me wrong, I have my achievements, but if I wasn't dating, I would have had time for more important things like scholarships, school, physical fitness, etc.
But as for advice for dating, all you got to do is not rush into anything. I known my gf for 3 years before I asked her out and now we got a great relationship. Great things take time, but the quicker you rush it, the quicker it ends. Just be yourself and have confidence. Confidence is a key to getting girls, that is why all the cocky or coinceded guys got all the hot girls. lol. But remember confidence is the key that really attracts girls.....
