I'm gonna agree with some of the stuff already mentioned, and then suggest some other stuff.
1. Online dating can be effective, but it can be pretty brutal. Studies indicate that a very small percentage of guys get the majority of responses on dating sites. If you're tall and good looking, you'll be in this group. If you're not, you'll be going after scraps. If you decide to find women online, do yourself a favor and actually read a book or two on online dating. Find the ones that are written by
men. Learn how to write a good profile, get good photos (critical), and not waste countless hours online.
2. Don't forget meeting women in real life. It's a lost art, but I still meet women occassionally at the beach, bookstore, coffee shop, etc. I don't force it, but real life conversations can occur and can lead to something. Every time I met someone this way, they say "wow, it's nice to actually meet a guy in real life".
3. Leverage your friends and their wives/gfs. Have them introduce you to the single women they know.
4. Get yourself squared away if necessary. You may have this already dialed in, but remember to wear well-fitting clothes, be well-groomed, etc. You are working out regular, right?
5. Don't waste a ton of time or money on first dates. Don't drive long distances. Keep 'em quick and inexpensive. Dinner or even drinks can add up quick when you're going on a lot of first dates. And you'll find a ton of women who are bigger or less attractive than their photos indicate. First dates should be short and sweet, and cheap.
6. Don't settle. I have successful and decent looking buddies who have settled for lower quality women simply because my buddies got lonely and discouraged. That's weak. Personally, I've been through some lengthy dry spells, but I know from experience I'll eventually get though it and end up dating someone I am really attracted to. Don't settle.
7. Learn about the male-female dynamic. Intergender relations are vastly different than what we learned in school, and disney films, and romantic comedies. Rollo Tomassi's "The Rationale Male" is a great place to start and should be required reading for all boys in high school. And recently divorced dudes.
