I don't think I can do SRS. My dopamine system is at a point where I can't do anything for a long time that isn't interesting, has immediate or intermediate rewards, or can capture attention for a long time. And on top of that, repeating that habit requires all these criteria.
Examples:
Scrolling on the phone?: Basically direct dopamine injected into my brain. Can do indefinitely. Not good.
Programming? Sure I can put a few hours in, or even days if building quick prototypes where the payoff is imminent.
Reading? Can go on indefinitely, depending on the book: it's just continual stream of interesting immersive stuff
Exercise? Well that depends on the activity. Running indoors without any stimulation: absolutely cannot do. Cycling or running or walking outside with an audiobook, or music? Absolutely: constant stimulation plus endorphins.
Learning Piano? Only if I can bang out a few good tunes immediately in the session, then I can allow myself to struggle with the difficult stuff in between. Absolutely cannot and won't do rote deliberate practice. This hinders my progress significantly, but at least I have fun.
Learning a language? Well, unless I can get imminent rewards, or be continually interested and engaged, there's just no way I'll be able to do this. And I feel like rote, deliberate practice is just impossible for me to build a habit out of.
One way I know for a fact that I can learn another language is through necessity to communicate with it. Let's say I'm thrown into an environment where the ONLY way I can get anything done is through having to communicate directly, without the aid of translators or tools. I think this is how babies learn.
