Preparing for old age is something that must be thought about and must be done. But as you said not everyone can do that successfully. Sometimes what happens is not in accordance with the expectations we want because of things that are not planned.
But that should not make us give up, and try to live life without any purpose. We have to do hard work in order to realize the old age we want. Because we don't only think about ourselves, but of course we will have a small family that must also be happy and we guarantee its welfare.
We need to prepare now so that when we get old there's no need to worry about anything and everything. If you will see it is too early to prepare for things but then life is full of uncertainty. Having a good plan will also benefit those people around us and also our family. We should also need to learn to rest of course, as much as we work now we need to rest as well.
It's easy to say but not easy to do, our lives are not only about ourselves but also our families, parents, and children…a lot of things for you to worry about rather than thinking about the future when you're old. You can only save for the future when you have completed the above tasks, and that is not easy for anyone. I believe all adults know it's important to prepare for old age, but how to do that, that's the question.
