What can I do bro/s/? I'm 26 and feel like my life is already over.

I didn't believe in myself when it mattered and now I feel I lost out. I was admitted to a program I wanted to go and chickened out because I was scared.
Should I go for the CS or math undergrad and graduate with 29? Or should I work first and code on the side?

I feel lost and thought we might get our own support group going on /sci/ because there might be more of us here.

Methuselah star

the concept of “duality” in physics over the last 20 years is by far the most significant paradigm shift we’ve seen in physics in recent history. dualities between string theories, between gauge QFTs and string theories, between theories of the very weak interactions and the very strong interactions—these have all arisen and called into question what direction physics is moving toward. a reductive theory of the very small may and probably does map directly into theories of the very big and very emergent, in general.

this kind of modern approach to physics is still what is being absorbed in the research community today, and normies are completely left in the dust to discuss the past century of physics.

same with mathematicians. so out of touch

I am completely convinced that so-called mathematics is actually mental masturbation, and the only thing it really allows us to do is to create meaningless symbols to confuse us. If we could somehow get rid of these symbols, all our problems would be solved. This is not unlike most religions and their God. A bunch of fictional nonsense that helps us cope with life's serious problems. If you seriously think about it, mathematics is a dangerous pseudoscience that claims that 2+2 = 4. What difference does it make if we believe it or not? We still have to pay the bills, feed our families, and put a roof over our heads. When was the last time you used this "equation" in your daily life? I guarantee it won't help you in the least. Mathematics is not some kind of truth, it is a dangerous cult dating back to Plato and ancient Hellas. We need to put that behind us and pursue a more practical and useful science of mechanics that can be applied to real-world problems and that doesn't have the gimmicks of "calculus" to protect ourselves from reality. Don't lie to me about bitcoin and the digital age. Your abstract nonsense is only useful to confuse and mislead ordinary people. He has no place in our world. So I ask you again, why do you continue to believe in 2+2? What makes you believe this?

Order book day trading hasn't worked for 20-30 years. Please don't day trade. You will not make money in the long-run.

Sure you will in the short term. Everything has been going nowhere but up, with high correlation. When this trend moves against us, though, a lot of people are going to be left holding the bag.

>>13113174
The best thing you can hope to do is swing trade momentum on a multiple day - weeks basis. Stay on top of your risk management, and hope things don't go south in a correlative fashion.

What does the curve look like for age vs learning capacity? Obviously kids and young people are much more able to absorb information, but how steep is the drop and when does it start to seriously decline?

Im going to be 28 soon and I'm wondering if I should even bother trying to study intellectual topics at this point. I'm a high school dropout NEET, and while I've always been interested in science, math, technology, etc., I've struggled to get beyond the basics due to a lack of motivation and discipline.

Should I just give up on intellectual pursuits and accept life as a wagie?
