Lessons from the Edge
A few years ago I was involved with a network marketing company which was an excellent business school. Among the many things I learned, in addition to not being a very good salesperson, is that to be successful you must always be coachable.
This does not mean just to being open to criticism. Which if constructive, can be very helpful. Staying aware of areas you may need improving, being humble and asking for help. Also, acting on the guidance you have asked for. Read books, articles and posts in your area and stay current.
We are all skilled at what we do and all of us have areas that could be polished.
Find a mentor, an actual business coach or buy a colleague you admire a drink and nourish your success by keeping fresh perspectives streaming in.
