1. G-d knows who your soul-mate is
Worry about your relationship with G-d and let Him worry about your soul mate. Marriage is a higher level of serving G-d. Once He sees you are at that level, he will deliver your soulmate.

2. Your soul-mate is already alive
A) Develop your relationship with him/her. Care for him/her, love him/her, create a place in your heart for him/her. Pray that your soulmate is nearby, emotionally and spiritually stable.
B) Develop the integrity that you'll have when your married, now. There are certain things you would not do if married, i.e - watch certain movies, go to certain places - stop doing those things now.

3. A Jewish marriage is an intimate and private experience
Develop your ability to be private about your life and G-d will give you what to be private about: your soul-mate. Marriage is like the Beit Hamikdash, the bedroom is the holy of holies. The holiest aspects are hidden and kept secret. Certain areas of a person's life should not be public knowledge.

4. Spiritual/Sexual energy
Spreading your spiritual/sexual energy with the opposite gender pushes off ones finding ones soulmate. End all platonic relationships and watch the magic happen.

5. Good marriages come from work
Throw away your wish-list of the perfect mate, ie, the no-work marriage, and commit to working on your marriage. Rather, make a list of three things that you can't live without in a spouse that are not generic to that gender (like a giving wife). An introvert might need an extrovert.

6. Know and love yourself
We are only capable of committing to the decision of marriage once we know and love ourselves. It's important that we love everything about ourselves. Including things in ourselves we are not especially pleased with and need fixing. Loving ourselves makes us present to other people to make the right decision.
