No, this is horrible advice to give any trucel.
I am nearly 40 and aside from the fact that I was too ugly/short to have a family, my biggest regrets is that I tried. I went out, earned a degree, became a licensed professional, continued to advance and earn money, ect....... I worked out, I dieted, I forced myself to invest countless hours into being social, trying online dating, talking to any woman who would give me the time of day, ect. It was all a waste of time. The money sits in a bank or in stocks doing nothing. The house I have is nice, but I don't even use half the rooms. I don't even work THAT much compared to most other professionals but I still work too much considering I don't need most of what I earn. And all of that socializing got me nothing but a few "friends" who use me like a betabuxxing whore or as a tool to try to meet women.
My advice to any youngcels is to accept that it's over. Do what you need to do for yourself to get by. If you truly need a fancy car and big house to be happy then careermax, but most men don't. I would have been better off working a shitty part time job, living in a one bedroom apartment, coping with video games or TV or even drugs and booze. Instead I work for money I don't need to support a society that hates me. It's like a sick joke.
I guess this only applies if you know you are a trucel though, at 19 I was so niave I thought getting a good job would ensure that I could get at least a semi-decent wife, and I didn't even think I was that ugly. But if I knew then what I know now I would have gladly joined the great decline, doing just enough to skirt by. I still wouldn't have been happy, but maybe I wouldn't be so miserable either.
People deny it when talking to incels, but otherwise they always say stuff like "Family is everything" or "Your true wealth is found in your wife/children" or "Family is what makes life worthwhile". It's all true, at least for a man like me. Even raising my animals is just a shitty cope. Money, professional status, expensive crap..... It's completely meaningless without a family to share it with.
So why work so hard for something that will never benefit you?
