Let's break it down.
Step 1: decide on what you want to focus on. It could be the cover of your brochure. The first email you send to a parent when they enquire. The experience a student gets when they first talk to you. The way you label folders. Or even your ringtone.
Step 2: get into the zone. Sit in the sun. Or find a quiet corner. Listen to the birds. Or the music that gets you going. Silence notifications. Hide from the world. No excuses.
Step 3: study it. Look at it. Read it. Listen to it. Experience it. If you are looking at some marketing or comms piece, imagine the effect it has on that student or parent. If you are looking at something that you use, think about the effect it has on you.
Step 4: tweak it. If you feel it could be slightly better, change it. Try different versions. Just remember, it's a tweak, not an overhaul.
Step 5: admire it. Be proud of it. You've just made something you do even better.
