Based on my experience this is how you can save money easily:
Always think about NEED VS WANT.
Avoid eating at the expensive restaurant .
Always follow thw formula: INCOME -SAVINGS = EXPENSE
Make a budget plan and monitor it.
Look for extra job/sideline to have an extra income.
Have faith that you can save do it.
It is not easy to save money especially when you get older because as we get old, our needs in everything increases. We want to buy that,this etc. I think that the first thing that we should do is to have drive or willingness that we can save money despite of many distractions. We should also have discipline on what are the things that we buy. We should measure it we badly neede it or we want to buy it to fulfill our satisfation.
