Saving money over the long term is not difficult but very few people have the will to do consistently, this is why saving should be taught from a very early age, I have been saving money since I was a kid and now I am saving bitcoin, and I will not be surprised that I will be the person in the best economic position of my family in just a few years despite being the youngest member.
Yes it's good to save from an early age, the main thing is simple life because with a simple life you will not be too often to spend money on things that are not really needed in your days. By having a consistent lifestyle that is simple then I'm sure we will be able to save money for a long time.
