I'm not the best writer, but it is a strength. I might be a 90th percentile writer.  

And I'm not the best marketer, but it is a strength. Again, maybe 90th percentile? I'm better than most, but if you pass 100 people on the street it won't be hard to find some people better than me.  

What I have gradually learned is that it is not your strengths, but your combination of strengths that sets you apart. It is the fact that writing and marketing are mutually reinforcing—and that I enjoy both—that leads to great results.  

How can you combine your strength? That's something I would encourage everyone to think about. You will find talented people in every area of life. It's the combinations that are rare.
