A few rejection letters and finally his first assignment and his reply. All of these were shared by Jim Lee on his Instagram page.

1988 - Lost Liefeld New Mutants story

Grabbed from http://robliefeldcreations.com/?p=3013:

"...I was given an inventory story written by Howard Mackie featuring X-Factor and the New Mutants. This is well before I would introduce Cable or Deadpool in New Mutants, this was the pre-Cable cast of characters. The idea was that it could be scheduled a either an X-Factor or a New Mutants fill-in story. The focus of the issue is heavily trained on the character of Warlock and his fascination with a character named Madcap."
