I've found that you can never stop learning, whether that is in my professional career in the area of finance or in my hobby as a photographer.  I've taken classes at my local photography shop to help improve.  I can no longer claim to be simply a 'travel' photographer.  I've worked with friends and family to improve.  I do portraits, action, sports, and more.  The experience has been fantastic.  I only hope that my family and friends don't tire of my hobby.
