Has anyone influenced a sibling to be frugal?

nail on the noggin. i have a cousin thats in his 30s, doesn't listen to a damn word to anyone i think. it is infuriating at times. here is a small list of things his stubborn ass has done:

earlier this year he bought a graphics card for $300. the price was perfectly fine for the card/brand. his old card was a 5 year old $200 card. there is something wrong with it, i dont know what. his PC has been reformatted since getting it, and had drivers reinstalled, old drivers, everything. but it has a lot of graphical errors in games. i told him to RMA it. the company will pay for the return shipping, and he has his old card to tide him over for 2 weeks. "nah ill just buy a new one" because he is too fucking lazy to go to the post office before 11 am on a saturday morning, or go on his 1 hour lunch break at work.

in ~2012 he bought a used ps2 from gamestop for about $100. i asked him why.. since we have had a ps2 since release that still works. he said "no, its broken".. i told him that he had to put 2 cd cases under the a/v adapter because it doesn't maintain contact. but a $5 adapter from amazon will fix it. he was still within the return policy at gamestop.. he did not return it and didn't even play it over a week. but now i have an extra ps2 in my closet.

he threw a perfectly good xbox 360 in the dumpster because he never played it. this was when you could easily sell them for $100-150 used.

he threw a keurig(actual branded one, still going for $80 on amazon) in the trash because he got a keurig that makes multi cups..

he quit his job(he has worked since he was 16) because he hated it. and started going to college fulltime. nothing wrong with that, at all. in fact, we both started college at the same time. we went to the same community college and then transferred to the same university. he got a part time job making ~9k a year, his wife made around 35k a year, and he had 50% off his tuition for his 60 hour associates. his mortgage is only $350 a month, no car payments, just regular bills. my rent was $350 a month, and just regular bills. i received no discounts or anything like him. he graduated with nearly 50k in student loan debt because he blew through the money, and i graduated with 14.5k in student loans.

i never made more than 15k a year while going to college, yet had 3x less student loan debt than him.

he bought an iphone 6+ on release.. which is fine. except, he was bitching about how laggy it is. i told him for about 6 months that it is lagging because he needs to go get a new free battery from an apple store, it will only take a couple of hours and the phone will be like new...nah, spent $1200 on a new phone even though he only uses it for texting and internet use, he doesn't even take pictures.

i've always bought glasses online because its the only way to afford them. i've never spent over $150 for ray ban glasses(hes obsessed with that brand..) for frame + lens. he always spend $400 minimum at the doctors office. i've consistently told him this for over a decade, but he still buys them for that much. at this point he is actually broke because of a few more reasons(no drugs or gambling at least) and just this week he said "you buy glasses online??" as if i haven't told him several times over the years.

i wouldn't call it laziness. because he has worked since the week he turned 16, has always held a job, got a bachelors in 4 years, has a ~1500 hour tech certificate in manufacturing.. but acts like he is too good for some things, even though he has never made over $20 an hour -_-
