Saving money is an important thing that we must make a top priority in life, if we don't save it will get a lot of difficulties, saving is of course according to ability, but if we have a small income then the first thing to do is take it for saving and the rest is for needs, if we don't do that then until we are old we won't be able to save.
I'll put the main needs first, then we can save the rest. Agree with you that saving should be according to our ability, so that we don't neglect our main needs so that we can save. The amount is not the problem here, the most important thing is that we can set aside money from our income for us to save, it doesn't matter whether it's a small or large amount, the important thing is that we can do it consistently. Many people who have a large income but they can't do anything for the future due to their luxurious lifestyle, which makes them unable to save their money.They got affected mostly by social media, which is why they will spend more on their wants, like if they just see a newly opened restaurant with a lot of people going there, even if it is not necessary, they will go to it, or buy a new phone even if their old one is still working. If people can't control this kind of urge, then for sure they can save for the future, as they are prioritizing their short-term comfort or happiness.
