ASK FOR THE CRITIQUE.
Ask for honest feedback on your work.
Praise is comfortable and useless. Send your work to someone whose judgement you trust and ask exactly where it is weak.

THE CHALLENGE
Send your work to someone whose judgement you trust and ask two specific questions about its weaknesses. Not for praise. Sending counts.
WHY IT'S HARD
Your real work is exposed to useful criticism.
DO IT RIGHT
Choose a real situation with someone you know and trust. Never pressure anyone, contact strangers or share their reply. No real situation today means skip.
HOW IT WORKS ON HARD.
Everyone gets the same challenge on the same day. Say I'M IN, take as long as it takes, then say I DID IT on your word. Your friends see you show up.
ON THE RECORD
IT COMES BACK. NOBODY KNOWS WHEN.
