What age would you guys say is a good age to get into a ltr?

I know trp recommends you spinning plates and girls will screw around whether in a ltr or not. I’ve always thought you should wait till your at least 28 to get into one because you should be building an empire right. I’m 25 and just recently gone back to college to be a programmer and hopefully start my own business in that field because I’m striving for excellence in that particular field. But it feels like every guy my age is having kids, living with their girlfriends etc. At the moment I feel like I just can’t compete with other guys around my age, as they have nice cars and more money while I’m at college studying for a better future.
