What is a lesson you feel you learned too late in life?

@Hope

I found out to love myself and not always put others first pretty late..... i did everything for friends and family but was always waiting for my moment .........

Now i know i am just as important and i won't let myself down and in doing that i see what time i wasted and Time you do not get back ever.... you can make more money meet someone new fall in love again but you can NOT turn back time.
