This advice is thorough, but as the author admits a bit autistic. It approaches a relationship as a specific highly-fixated goal that requires reps / practice.

In general, I think any guy trying to do this is not going to find what they want.

I can only give my own (likely more applicable) advice to other straight men on here (which I suspect is a very high % of the users), but I would ignore much of this advice and do the following:

* Live your own life to the fullest. Don't even worry about dating / the apps. Just do activities you love and develop a passion (or more than one!). The apps are basically designed to mess with your psychology and the yield of your time spent on them is very low unless you are extremely attractive (not me lol!). Start rock climbing and go to a bunch of meetups for it, meet new people, and be the one who asks people (men and women) to meet up for climbing. Copy-paste this onto whatever activity you want (I've done it with skiing, climbing, mountain biking, and sailing). You will eventually meet a partner through these group activities and you won't waste any time trying to "date", and often you'll be able to vet your partner in a less intense "setting" than a date. For example, you can talk about what money "means" to each of you while walking to the crag and realize that although she might be attractive, you'll probably just fight about money all the time.

* As part of a full life, maintain your friendships. You need to be able to lean on your friendships to fulfill specific needs that your partner shouldn't need to or be able to do. I talk about code with my coding friends, not a girlfriend. I nerd out about sailing with my crewmates, not a girlfriend. I talk about espresso with a bunch of deep-pocketed coffee nerds on discord, not a girlfriend. Think of spending time with friends in the same way you do the gym: it might be tough to fit in on any single "session", but if you stop doing it after a while, you'll find yourself really behind the 8 ball. If you think you can't afford the time, I can almost assure you that the time spent in the company of friends will so vastly reduce your mental rumination / anxiety / depression you fight when you spend so much time alone that the "friend time" will more than "pay" for itself.

* Know what you want, and communicate it clearly. If you're looking for something low-key, be clear to your partner. If you are angling to get serious and move in faster, be clear about that. Most of the friction in relationships comes from when each individual is on different pages about the trajectory of where they want things to go.

* Talk about money. I see so many couples don't do this and perpetually fight over things that come down to "what does money mean to you?". For example, if your partner gets a tax refund and thinks "oh boy! let me buy a new computer" while you think "give me my interest-free loan back, US government, so I can shove this into an index fund and have greater financial security to tell my employer to kick rocks if things get too terrible", you're gonna have problems reconciling that unless you're very explicit.

* Table stakes are similar to the article though: stay fit, eat well, avoid mental numbing mechanism and substance abuse
