Never forget the beginning, never forget the beginning

不忘初心方得───Don't forget the beginning;始终───throughout

Dear, if we forget that beginning, please don't forget the ending.───亲爱的，如果我们忘记了那个开始，就请不要再忘记这个结局。

Don't forget, from the beginning I repeated one simple thing, man USES 20% of energy needs through consumption of the food and 80% of it comes though environment.───不要忘了，从一开始我就在不断重述一个简单的事实，人体只有20%的能量是通过食物吸收的，而其余80%是从环境中吸收的。
