I found this over on Jonathan Hearns blog who found it on the Muddy Colors blog - great tips and advice here. They can apply to anyone who works in a creative field.
1. Get up happy. Say some affirmations. Get rid of the negative chatter in your head-that voice that says things like, “I’m not coming up with any good ideas. I’ll never make this deadline. I’ll never be good enough to do this job.” Instead, train that voice to say something positive. Reprogram yourself. “I am illustrating books that people love. I am happy with my art. My career is going great. I am a successful artist…” This might sound too simple, and you’ve probably heard it before from the self –help gurus. Have you ever actually tried it….consistently over a few months?
2. Exercise and stay healthy. This is not an option. When you feel healthy, you are more open and ideas come more quickly.
3. Sit quietly each day, do yoga, or meditate. Get calm and peaceful so that when the ideas come, you actually realize they are there. Worry, anger, fear, and other emotions actually block the ability to grasp those sparks of imagination. [Spend time off of your iPhone, Twitter, Facebook - a whole day if that's possible!]
4. Create a place and time to be at work. This is important if you are working at home. Your mind needs to understand, “I am now at work. I will now be creative.” So sharpen your pencils, put on music, sit before your drawing table and begin.
5. Don’t talk too much about your ideas; this depletes some of the magic. On a subconscious level, your wonderful idea has become a real thing in the world. It’s not real, and it won’t be, until you do it. So, instead of sharing your magnificent thoughts, go make the work happen.
6. Take time outs doing something you love. Go to a museum. Sit by a lake. Walk though the woods. You must replenish yourself. Fill the well. Don’t view this as goofing off…this time is very important.
7. Don’t be a workaholic. This is difficult, because you won’t know it, until it’s too late. Your friends and family will know it before you will. ONLY YOU CAN CONTROL THIS. Be the work police and set your own boundaries. Make a contract with yourself. “I do not wok on Tuesday and Sunday. I go on vacation without my work. I have lunch with a friend on Friday every week. I only work from 9am to 2pm. “Put up a sign. Remind yourself that you are free to set your own schedule. Work as late or as little or as early as you want, but make sure you’re enjoying the pace.
Remember, somebody you know will be published before you or more often than you. They will be more successful. They will sell more books. They will get more speaking engagements. You think you will never make it. You won’t…unless you stop working so hard to catch up. Find your own pace. Find your own style. Do what works for you. Be patient. Change happens in incremental ways. When you consciously make these daily choices, you will see a big difference in your life over time…and you will be balanced enough to notice!
