When you are frustrated by it you lose focus on what matters

Traffic can distract you even after you park your car. Have you ever been excited about where you are going when you start heading there but by the time you get there you are frustrated. I have learned to leave a few minutes early so if there is a traffic jam it doesn't matter. If you know it takes a minimum of fifteen minutes to get there you are forgetting what the "minimum" means. It means if there is no traffic or you don't get caught at every red light, it will take fifteen minutes. We all know that there are times when you do catch nearly all the red lights on your way. Road rage is dangerous to your health. Getting frustrated raises your blood pressure which is exactly why you should always leave a few minutes early. You can eat healthy and get plenty of exercise but to maintain your overall good health you have to pay attention to your mental health. Getting mentally frustrated and raising your blood pressure will do as much physical damage as laying around eating french fries all day.
And what if you get a flat tire on your way. You certainly won't be able to to get where you are going on time if you don't leave a few minutes early. Arriving five minutes early won't frustrated you or raise your blood pressure. The healthy choice is to choose to leave a few minutes early. Next time you find yourself stuck in traffic and you feel your blood pressure rising because you know you are going to be late, I hope you decide for now on you will leave a few minutes early. It's not only what you eat but what's eating you mentally that determines your overall good health. You could only be a red light away from a heart attack if you don't leave a few minutes early.
