Why is attitude the most important fitness level factor to consider?

If you keep a positive look like how you are keeping healthy by exercising. When talking about your fitness level, proper nutrition, supplements, cardio exercise, and weight training are all important factors, but it is your attitude that determines how hard you focus on each of those areas. Attitude is very important just keep your attitude positive.

Because without physical activity, the body has extra "energy" if you will, and so when it is time for bed you are not tired, so you end up staying up all night. also there is probably an effect on your internal clock, which messes with your melatonin production which goes hand in hand with your sleep cycle
