Shidduch for men – 2 hours of שמירת הלשון (the Sefer) a day no lying to yourself about time spent in the text and taking notes. On top of thatתענית דיבור 2 hours a day, no clown stuff on your mind just pure clear thoughts(As רב נחמן called it התבודדות like in Coronavirus means to isolate, so take time off from the תרבות המערבי and just clear your head two hours a day.) Do this for Three months and then go to a Shadchan.
For Women- צניות!! This one is a big deal, if you have גאווה at all in any matter whether that be תורה, חסד, ממון, Family accomplishments, Social circle, etc. all that type of גאווה will destroy the potential for שכינה in your current and future home. ליבוש צנוע as well is a big deal it reflects on your מידות as a whole which of course applies to both Genders. I suggest for women תהילים as well תפילה for Women goes a REALLY long way, like a REALLY REALLY long way…
