I wrote this post a while ago. These concepts are from a wonderful shiur by Rabbi Eliyahu Kin. I found it very helpful, and I hope y'all will as well.
Before a person dates, (s)he needs to be ready. There're three prerequisites a person should fulfill in order to be ready:
1. Not be picky (being particular about a certain look, financial income, etc.)
2. Not purposely delay marriage. (For example: I'm not dating now -- I'm too busy with my masters. When I finish my masters, I'll date.)
3. One must examine his deeds and make sure he's done his best to keep the Torah and mitzvot.
Because there're many individuals whom you can be compatible with, but there's only ONE who is best for you.
People are only shaliachs. HaShem is the One Who makes the shidduchim. Only He knows which 2 individuals match well together.
If a person isn't acting on their "best" behavior and working towards growth, then that person will not receive the best possible zivug. You're matched based on your current deeds. HaShem sends you the best possible match at a given time.
Now, let's say all 3 conditions are met. What do we do now??
Chazal quote a pasuk that says one should always turn to HaShem. One should pray because prayer can change any degree, regardless of what a person's mazal is.
One should pray that HaShem should please send him the best possible match; the right person who will also be a good person.
During Shemah Kolenu and the "yehi ratzon" at the end of the amida, a person should have zivug in mind, but he doesn't have to word it out.
Simple concepts a a man should have in mind:
-I want a wooman who will be an eshet chayil, who will be a good mother to my kids, and someone with whom I can build a bayit ne'eman b'yisrael.
Sefer Hassidim teaches to pray for your children to have good zivugim.
Hishtadlut shows HaShem that we are serious about finding our spouses.
The Chazon Ish taught that tefillah is more important than hishtadlut.
Men should give tzdaka at Shul when they go for minyan. Women should give tzdaka before lighting candles for Shabbat.
Charity can hasten the results; it makes a person's tefillah be heard all the more so.
The gates of tears are never locked.
Tears are an expression of the emotions of the heart.
And most importantly, NEVER give up. Ye'ush (despair) is one of the most crushing emotions an individual can experience.
Daven. If the situation gets more difficult, daven harder. If it's nearly unbearable, daven x100000000!
