Financial stability just means I have to respect my financial limits, never spending money I don't have or that I will miss later for emergencies.
Your definition of financial stability sounds like you are emphasizing about the importance of saving money for better future. Different people must be having different opinion and hence I just agree with you because without having enough money, we cannot think about a stable lifestyle so saving is more important to think about financial stability.
Always having some income stream to lead our life stable could be defining what I feel financial stability should be like.
I do not believe that you could simply save enough money to have financial stability in this day and age. You really need to invest with that as well. This is why I save some aside, and use that to buy crypto as well. Otherwise, how much could I save per month? Even if I save up 100 dollars per month which is a lot for where I live, that would be still a huge amount and not enough, that would be 1200 dollars per year and 36k dollars in 30 years. Imagine working for 30 years, saving more than 1/3 of your nations minimum salary, and still not making enough to retire.
This is why I can't really make any kind of saving be valuable for me, it is just not enough. However in 30 years, if I could 100x that, which as we all know quite possible in crypto, we are talking about 3x more time in crypto then it existed, a whole 30 years, 100x is quite possible. In that case your 36k suddenly becomes 3.6 million dollars and that is WAAY more than enough to retire.
