Athletes and musicians practice playing for a reason, it’s silly to think that you shouldn’t practice and learn your own craft to better keep up your skills.  Even if you’re number one now, you need to find time to keep learning to stay on top. You have to continue to challenge yourself and figure out what’s new and how you can stay ahead of the curve. When you keep learning and growing you stay hooked on your craft, it never get’s old. If you love what you do you’re going to get better at it. Learn every aspect of your business, if it’s the book keeping, sales, coding or customer service. If you understand the entire business you’ll know your craft better, you’ll know the issues that can come up before the other guy and you can call bullshit when someone is trying to tell you how it should be done. Keep finding ways to grow and challenge yourself because as soon as you stop growing, your passion for your craft could fade away.
