Energy: One of the most important things, if you have a desire to work hard and make good money, is going to be that you have the energy required to do so – and not just the physical energy, but the mental energy as well; when you eat poorly and take improper care of your body, your mind and body will both become fatigued far more quickly than they would otherwise, and this is one of the main reasons why keeping yourself healthy and taking good care of your body are vital: this will help you have more energy, which will make working hard a whole lot easier.
Stress: When you are eating well, getting a good amount of exercise, and allowing your body to get a proper amount of rest, your body will be far better able to regulate stress levels and keep your body and mind at peace – and of course, when it comes to “being able to work hard,” keeping your stress levels low will be important; when stress gets to you, it will be far more difficult for you to work hard – and work well – than it would be for you to accomplish this with low-stress levels.
Longevity: And of course, eating healthy and taking care of your body will lead you to have a long, happy life – and this means you will have a lot more time to enjoy the wealth you have accumulated from all your hard work than you would have if you were unhealthy, and were on track to check out of this life earlier than expected.
