Untrained people (and semi-trained people like me) can’t sustain focus for extended amounts of time—even if I set my mind to the breath, it will slip away.
What I would say is that untrained people don’t sustain focus on their breath for extended amounts of time. When you introduce the word “can” you’re claiming more than just what is observed and making claims about what they would do in other counterfactuals too. If we’re careful with those counterfactual choices, I think the claim that they “can’t” turns out to be false.
The difference between “trying to try” and “trying on the object level” can be the difference between struggling for months and succeeding in seconds.
I do not understand what you mean with “There can be though, if that’s what you want”. Do you mean “It’s possible to will/train yourself to have a coherent self”?
Something like that, yeah.
Like, you might want to go get Chinese food but not spend your money. Your desires for Chinese food and money are tugging you in different directions rather than in one coherent direction. But it’s possible to make up your mind and coherently want to pay for the Chinese food or else not want to eat it. You have to recognize that you can’t have the food without paying the money, and figure out which of your new options you prefer.
Do this enough, and you become relatively more coherent.
This is what I’m talking about. Defaulting to the third person perspective and forgetting about the first person perspective causes a lot of trouble. It’s not just “here’s an unrelated hack for making it easier to do meditation”, it’s that it completely changes your meditation.
You notice that your third person “I should focus on the breath” is missing the point, and redirect to the first person perspective of “Sensations of breath are arising”, but in doing so you no longer even have a claim to the relevance of the breath. So now you have an experience of attending to sensation of breath for no reason, because of fairly handwavy third person reasons.
I’m pointing out that you can use meditation as practice for bringing more conscious awareness to your everyday life by bringing more conscious awareness to your practice of meditation itself. It’s a very different experience when you know in first person why what you’re attending to is the most interesting thing at the moment, and in third person knowing that you’re right to think this is what’s worth attending to.
That doesn’t mean you “give in” to first person perspectives and give up awareness of your third person perspective, just that you don’t give in to third person ideas either and give up or attempt to disconnect your first person perspective. It’s practicing being aware of both, and noticing when your behaviors don’t make sense according to your own perspectives.
