That’s all reasonable, and everyone is different , but I do think your original comment needed pushback, because meditation is often portrayed as enjoyable and easy at least in certain kinds of media. And I do think a lot of people give up when they find it boring and painful on their first practice.

And for me, it is boring and painful AND useful. And took weeks to start to show any benefits at all. Sort of like going to the gym. And people should know that that is a common thing, that you might hate meditation practice but still find it useful and continue.

You should include the same advice that is given for exercise, it can and should occasionally be a bit painful but you have to discover your safe limits and only push yourself a little past them each time. You don't want to rack weights in 45lbs increments until you tear a muscle, you do it in 2.5lbs or 5lbs increments and practice for several sessions of work/rest at the same level for a while before making another small increment. People often quit both exercise and meditation because they just try to push through the pain and often end up with negative results due to injury or emotional and cognitive strain in the case of meditation.
