Kinda difficult to know where you set the boundaries for what, if any, is allowed behavior based on emotions and what is not.
How do you live a more "rational life"? (Usage of the word rational in this context: not governed/ influenced by emotions). What are you supposed to do with your life? Work towards? What are the principles? Why is it rational to spend more time learning priorities and utilities? Is being the ultimate work bee the life of a rational man? What are the values that dictate what you should do?
We all let our lives be dictated by our emotions, it influences who we are friends with, what hobbies we choose, for some their job, who we have sex with, what food we eat and sometimes how much etc.
I don't see why you should try to run from your emotions, I consider it more in terms of taking advantage of how you function in a way that benefits yourself. So, if spending time with a few friends playing videogames and shit gives my biological body joy, that benefits me, even though you could argue rationally I should be studying or making money (again, not sure what the optimal rational life is supposed to be, to me that doesn't automatically make sense if you take into consideration how humans actually tick).
Some feelings can be utilized without detrimental effect to your life, though some slight detrimental effect tends to be tolerated to improve the pleasant feels known as life quality. Like smoking, drinking, eating bad food. Reading a fantasy book would be a pretty benign example of catering to your feels.
Another example would be if you're irritated by people who follow their emotions, that's a feeling that's disadvantageous to you, unless it improves your function, you enjoy feeling irritated and obsess over something that doesn't need concern you (in the instances it don't) or otherwise get some sort of useful reward from it. It's probably much more advantageous to learn to understand why some people are more driven by their emotions.
You could even say it's irrational for you to spend time typing up that post. Wouldn't your time be better spent learning a new language or focusing on "learning priorities and utility"? Then again, it's difficult to know what your argument is exactly, and where you draw the line. Obviously a lot of the things you spend time on, on intpf isn't driven by the rational mind, but rather some need for certain types of emotional outlet.
Unless you think it's rational to follow some feels to improve the vague concept that is life quality. In which case you are acknowledging following some emotional whims can be rational. And if it is, you didn't do a good job of communicate that. But then it's an argument of where to draw the line. And I think most people agree extreme and destructive emotions are bad, but that doesn't make them go away. For instance, if you were abused as a child, you might have pretty strong emotions as an adult that makes you do desperate things like drinking or self harm. These types of experiences tend to get stuck in a person, because that's how we tend to function. It's not as much choosing to cater to your feelings, as trying to block an incoming boulder with your hands. In some cases you can learn how to redirect the boulder, which is quite the complicated art and might take years to fully or partially do.
It's not really the matter of being born the superior rational person, it's more of a lottery of what you experience and how your body and brain function and process those experiences + how you are taught to process emotions. And stuff like that. Some people detach and think that means they are in control of their feelings. Some people are never taught to process their emotions from their parents and might "overreact" to small things as adults. You put boundaries and expect better from them in some cases, but it's also limited how much you can blame them for being a product of neglectful parents. It's important to separate blame and irritation, with allowing, though. Just because you understand something and don't necessarily blame someone, you shouldn't allow yourself or others to be treated badly etc.
