Sometime ago, I was discussing with a friend then I told him "my mentors don't even know they're my mentors" , we bursted into laughter. But that's the fact, I won't be dwelling much on that right now.

Certain people stroke the fires within you to be all you can be. when you find them, feed off them! when you have little or no water in your own well, be willing to draw it from others.
“If I have seen further,” Isaac Newton wrote in a 1675 letter to fellow scientist Robert Hooke, “it is by standing on the shoulders of giants.”
Ironically, this Newton’s phrase wasn’t even entirely his own. The phrase can be traced back to the twelfth century, when the author John of Salisbury wrote that philosopher Bernard of Chartres compared people to dwarves perched on the shoulders of giants and said that “we see more and farther than our predecessors, not because we have keener vision or greater height, but because we are lifted up and borne aloft on their gigantic stature.”
If seeing others succeed makes you want to sabotage their success, you'll never prosper. learn how to rejoice over the blessings of others, and realize that the same God who blessed them can bless you too. let their blessings challenge you to reach higher.
