Similar boat here.
Ever since I realized over years and years just how much looks matter (starting when I overheard how much a group of girls a year above me when I was 14 liked my lean torso and despised the somewhat pudgier torso of another guy), and that I would be left in the dust by professional models, athletes, celebrities and local chads I saw and was shown if I didn't looksmax myself, I have made it one of my written goals to keep myself looksmaxed. Good diet, gym, decent style and haircut, posture, microneedling, PRP, skin lotion, hair retention, laser eye surgery over glasses or contacts if I ever need it, hormone replacement if I start to need it... I am on that sh!t. It doesn't just get tied to your selfesteem as a positive reward, it's also the dread of knowing what awaits if you don't do it. But the feeling of being on top of your game makes it feel good too.
The halo effect of looks is fvcking huge in all aspects of life. If I have any I will tell my children that looks, a marketable skill and again looks is the fundament of life. You live in different realities not just sexually but in all of life depending on your looks.
My attitude is that as a man, you are evolutionary chaff unless you put in effort not to be.
I kinda miss doing mma.. but if you don't live only for it, then it only works if you have a decent group of sparring partners. If you have sparring partners who are less concerned about chronic injuries or brain damage than you are, you have to change center or quit.
Funny thing is that the guys who tell you to just pursue your hobbies to get girls obviously have never set foot inside a martial arts center lol. Either exclusively male, or worse gender ratio than Tinder if you are lucky with the class/center.
