Answer: an important lesson I’ve learned in my life is to NotTake Anything for Granted.
We often don’t appreciate what we have until it’s gone: that includes your health, your family and friends, your job, the money you have or think you will have tomorrow.
As we grow up, we always assume that we will always have our parents/best friends there for us, but in reality you won’t. Nothing in your life is guaranteed to be there tomorrow. Including those you love.
It has help me change my views on life and has taught me to be thankful for what I have while I still have it.
