Take it from someone who is far from rich, killer looks, or yichus (unless yichus atzmi counts).
Putting aside the top 10% of the population, (who are truly rich, and /or stunning) the vast majority of us are as plain as a lb of rye bread, yet satistics show, getting married (and happily, I might add) is pretty much a sure thing.
At engagement time, both of us were page 47 news. Now, 2 decades+ later, we’re prize winners.
Bottom line: don’t despair! Just be yourself, and be prepared to take someone who (like you) has 85% of “what it takes” (everyone has a diff yardstick, so I won’t specify what “it” is) and the remaining 15% is what you work on building.
Won’t comment on yichus, because its too subjective
