How can one find one’s true soulmate?

You don't find your soulmate, you develop one. It starts with noticing someone in your life who attracts you. Then as you get to know them you find compatibility between your two personalities, characters, and values, goals, preferences, etc. As you develop a relationship with this person, you and your partner both learn a lot about each other, figure out how to anticipate and resolve conflicts, adapt into constructive communication styles, and become precious to each other as you become even better suited for each other over time as you share a growing string of positive memories together. That's how you get a soulmate. I hope this helps and I wish you well. Comment or send a message if you have more to say / ask, follow me if you'd like to keep up, and check out my Quora blog. :)
