Invest a little money for your health as well as for your vacation because you should not only think about the possibility of getting rich in the future about your investment while your health and psychology are compromised. These two things are very important to think about because the body also needs healthy nutrition and the brain also needs relaxation which does not always have to think about money and money.
It's true to live a simple life, but you don't have to cut too much of your life just to prioritize investments. 5% to 10% of your total budget is also a good range for you to invest as long as it is consistent with it. So don't worry too much about it because life isn't just about money.
