On determination and all things related to achievement. No one ever said this thing (creating long lasting healthy habits) was easy btw! I am not one to encourage militarism but in times of war, both the best and worst of human nature is often displayed.
Here is one of the best, from arguably one of the greatest leaders of all time (call him many things but resilient and tough can’t be denied)
On October 29, 1941, U.K. Prime Minister Winston Churchill visited Harrow School to to hear the traditional songs he had sung there as a youth, as well as to speak to the students. When he was invited to give a speech, Churchill stood before the students and said,
“Never, ever, ever, ever, ever, ever, ever, give up. Never give up. Never give up. Never give up.”
Set your target and go to it!
