If someone is having a hard time finding a shidduch, what can they do to help the process along?
Are there any recommendations brought in the holy books that will make it easier?
The Talmud (Bava Kama 92a) states:
כל המבקש רחמים על חבירו והוא צריך לאותו דבר, הוא נענה תחילה
Anyone who asks for mercy for his friend, and he needs that thing too, he is answered first.
So you should consider praying for other people who have predicaments similar to your own.
