Pride can be a sin but a little pride in oneself is not. I’m not going to dye my hair but I sure as heck trim nose hair & ear hair, shave even when I’m not going anywhere and comb my hair. Heck, I even make my bed after getting up.
If I dress like a slob, I’m treated like a slob. I work to stay fit both because I enjoy outdoor activities that require a little athletic ability AND because I’m in my 60s and can’t stand old FAT slob men waddling around with stubble on their face.
As you said, “It’s about putting your best foot forward, confidence, caring about how you present yourself. Like anything it can be taken too far.”
We have become a nation of slobs. I see men who are middle aged and older going to church or sitting down in restaurants wearing short pants, message t-shirts, flip flops and baseball caps. In other words, dressed like eight-year-olds.
