Here is a good general rule that might answer the question: "If something happens over and over again, there is a reason." Rest assured that the reason won't be random chance or bad luck.

"Standards" covers a lot of territory. Some of them will involve deal-breaker issues and should never be changed (for all practical purposes, those should be few). But most should always be up for analysis in the light of current wants, needs, and situations. The more unbreakable standards you have, the more difficult you make your own relationships. Keep the standards that work for you, jettison the others. “Work for you,” those are the key words. If you like someone who doesn’t meet a prior standard, maybe that standard isn’t working for you and should be reconsidered. Keep your “bottom line,” those absolute requirements, to a minimum so people can more easily live up to your standards, and so you can delight in more people. You will be happier: “Behind every upset is an unmet expectation.” Give up an expectation, and you lose the upsets associated with it. Therefore, you should always evaluate, modify, and possibly cast off some of your standards.

Love at First Sight

Some believe, I never did
But on that night
I became a believer,
In love at first sight.

I never knew,
Love could have such a powerful trance
When my eyes came upon you,
I prayed for romance.

I’m not the type,
Who falls in love every day.
But to be in your arms,
The world I would pay.

I never did believe,
Until that night
When I saw you.
I now believe in love at first sight.
