Are you good enough?  The answer, of course is NO!  No one is actually as good as they could be.  I believe that every one, in every profession, has room for improvement.  Think of the best of the best in any profession you choose, and I can assure you they have room or improvement.  It may seem like they have some god given talent and are as good as it gets, and they may be the best, but they still could be better.

Let's use sports as an example.  Name the best player in your favorite sport (always a start to a great argument) and I assure you they have room for improvement.  Better yet, how did they become the "best"?  In any sport you can almost certainly contribute their success to work ethic.  They outworked their competition to get to where they are, and more importantly continue to outwork their competition to stay the best.  They still practice nearly every day of their lives to remain the best and continue to grow!  

Are you the best?

Actually, that is not as important as the following question.

Are you getting better?

If your not working EVERY DAY to improve your craft you are losing ground to someone that is out-working you.  Even if you improve yourself in something not related to your industry you will stay sharp and it will help you continue to grow, regardless of what you do.  If the best of the best still practice every day to improve their craft, why in the world wouldn't you.  

There are countless methods to growing and learning.  The internet is a very powerful medium to educate.  Here are some examples of things you could be doing to continue to grow.

1. Subscribe to a YouTube channel of industry/business leaders.
2. Follow a blog of your industry or business leaders.
3. Join a forum that is related to your field.
4. Subscribe to a email newsletter related to what you do.
5. Follow your mentors on Social Media. (Don't be afraid to ask them questions, they may just answer them).
6. Read a book! (any book, I promise you will learn something).

In our industry, I have seen multiple situations of very talented salespeople who have some very good months, but always seem to fall into mediocrity due to the inconsistency from month to month due to a lack of practice.  If you don't continue to work at what you do it is almost a guarantee that you will struggle from time to time.  I have fallen into his trap myself, and it did not turn out good.  It never does.  

In a world that changes at a warp speed pace, if you don't work to keep up and stay ahead of the game, you will certainly be left behind.
