This is a good writing day too:
Act: write that manuscript and submit it
Reflect: get rejected/taken on and drown your sorrows/celebrate with drinking chocolate
Adapt: double check that query letter and manuscript are exactly what has been asked for by the next agent/publisher, edit if necessary then submit to the next one.
You can do it... it just has to be the right manuscript to the right agent/publisher at the right time is all!
I'm at the Act stage with two agents and a publisher with two MG manuscripts atm, what about you?
