Use all possible ways of searching, and when a candidate looms on the horizon, do not rush headlong into feelings, do things differently. How? Think! Get to know your chosen one as well as possible, do not limit yourself to restaurants and cafes, go on a trip with him, go hiking. Test him, make him open up. Make sure you have a lot in common. And then make a "register" for and against. Describe your chosen one from all sides, identify his qualities. Do his hobbies suit you? Remember that a man can not be changed. If he loves soccer, he will love it until death. Are you okay with that? That's fine. No? Keep looking. Or are you willing to sacrifice something for him? Figure out for yourself what it is. Confront him with your friends, as clichéd as it may seem, but you can see better from the outside. Spend a few hot nights discussing everything you've experienced. Don't assume you understand each other without words. Talk about everything, even if it seems clear enough. It takes a lot of work to make sure this is your man for the rest of your life. But you have helpers: intelligence, experience, and serious intent.
