I am telling one real small story - One person went for a health check up. This is the real event I noticed in my life. I personally have talked with that person (Name is hidden). Doctor told him that he (the patient) had high sugar (diabetes). Therefore doctor prescribed him few medicines. The person immediately asked doctor to let him try with exercise. Is not be a good idea. Doctor told you also need to have these medicines regularly. The person made a determination in his mind. He daily woke up at 4.30 AM and he used to walk for one and half hour daily for same period in evening also. He completely changed his eating habit. One thing also to be noticed (this is my personal experience). Lazy men eat more than a fit man. After two months that person completely won on his diabetic level. Doctor asked him that had he taken medicines he told no. The person told about his lifestyle. Doctor happily expressed his view and told -NO PAIN NO GAIN. Hands up for you. Doctor also congratulated him for pain behind this gain.
