Like the guy in the beer commercial says... "Stay thirsty my friends!". Never stop striving to get better. Better at your craft, better at your business, massage your workflow, get smarter, learn from others, practice your people skills, learn to sell without being pushy, network, take good care of your clients and collaborate with your fellow professionals instead of always competing with them. The second you relax and you think you've got it all figured out, that's when the next generation starts kicking your ass. Trust me on that one!
