Proverbs 27:17 says "Iron sharpens iron, and one man sharpens another."
At some point in your life, you had the opportunity to learn from someone else. That is how we grow in knowledge and skills. You can pay for education by attending school or workshops. Think back about the people that played the biggest role in your growth in your career. If it was a teacher, they probably gave you that extra attention that you needed at the right time in your studies. That was not what they were paid to do. They just did it. If it was a co-worker or boss, they probably took you under their wing and coached you along the way.
The mentoring that you received that meant the most to you was probably not paid for with money. It was given to you as a gift from that person. We hear the phrase, "pay it forward", so often. Do not hoard your talents. Share them with others. I have found that the more that I teach someone about a specific topic, the more that I learn about it and I find my knowledge growing.
I recently had the opportunity to mentor a friend about self publishing a book. She had been trying for years and was discouraged about not making progress going the traditional route with a publisher. It did not take a lot of time on my part to coach her through the self publishing process and she was able to have a published book available through Amazon within about two weeks. The joy that it gave me to see someone else become successful was all that I needed to know that it was all worth it.
What are your talents? How can you share them with others and help them be as successful as you have been? It reminds me of a quote that I read. "I go for a walk and look at my foot prints." As you go through life, you have the ability to impact more lives than you can ever imagine. What kind of an impact are you going to make?
