Believe in yourself. Stay up all night. Work outside of your habits. Know when to speak up. Collaborate. Don’t procrastinate. Get over yourself. Keep learning. Form follows function. A computer is a Lite-Brite for bad ideas. Find inspiration everywhere. Network. Educate your client. Trust your gut. Ask for help. Make it sustainable. Question everything. Have a concept. Learn to take some criticism. Make me care. Use spell check. Do your research. Sketch more ideas. The problem contains the solution. Think about all the possibilities.
And the most important bit, have fun.
