I used to say this all the time with people.
I was such a wannabe know-it-all.
For instance, I gave a lecture to one person. (My lectures were horrible, such as "do not do this," or "do not do that." I was a huge hypocrite. Now, I tell you past stories and experiences from myself, my friends, family, relatives, and etc.) Then, he or she did not listen. He or she followed their own path. Eventually, I was right all along.
I said to him or her, "I told you so..."
I was a huge jerk.
Now, I say, "It is okay. You and I are still breathing. I make mistakes as well."
Nobody is perfect.
We are growing. (Give us time to grow.)
It is up to you. It is your life.
Like my high school PE coach said, "Life is all about choices." Thank you, Coach Marlon Blanton.
