Because you falsely assume one's attractiveness level or how good or bad their personality is actually has any sort of influence on one's likelihood of dating success.
The reality is in many cases this is not actually the case whatsoever.
Working hard to have an attractive and fit body and friendly, confident, social personality all increase your chances but do not guarantee or even make success very likely at all.
In my observations it seems for every happy, friendly, healthy, confident, kind, selfless, hardworking pair in relationships, there are two pairs of rude, selfish, greedy, unhealthy, unattractive, lazy people in successful and happy relationships.
This is the reason 'nice guys' tend to get so angry and frustrated when they're rejected.
They actually believe dating is a logical process! That you get out what you put in, you reap what you sow, cause and effect!
When the truth is relationships seem almost completely and absolutely random and by chance and some ugly rude slob who put no effort into even making friends can have plenty of friends and enter happy relationship after happy relationship their entire life while a fit happy friendly person can spend 5 decades searching extremely hard trying everything to meet men and women to date or be friends with and yet still be chronically single and miserably lonely and friendless.
Everyone has different tastes and likes different things, so if you're basically an average, normal guy, you're equal in attractiveness and chance to that fat ugly rude slob, no matter how much further down the self-improvement path you may be.
But, to be 'optimistic' about it, perhaps improving yourself as a person may see an improvement in the attractiveness of the looks and personalities of the women who give you attention. But that's not guaranteed or even likely either.
