No matter your personal faith preference, the words from the Good Book ring true:
"Whatsoever a man soweth, that shall he also reap." - Galatians 6:7
And that goes for the women too. (Sorry ladies!)
If you approach each day thinking, "What's in it for me?" then you're doing it wrong.
But if you approach each day thinking, "How can I serve other people's lives with my product or service?" Then you are doing it right.
And if you're not serving others with integrity, then it's time to change yourself or change the thing you're selling (or maybe even both).
If people in the world of sales would just grasp this pivotal point then the entire world would be transformed.
So go meditate on it. Ask yourself those questions. And if you feel like a change is needed go make it now.
You'll be glad you did.
