Under the Hot Sauce Gun

One Capsicum in the Chamber.  

"Under the gun": under pressure or attack

     -Merriam-Webster

I don't advise taking this expression as a productivity tool in a literal sense. 

Scale it back several notches, now we're talking.  Here is what I propose.

Hot Sauce Gun

• Fill a squirt gun with hot sauce.
• Put it next to your work space.
• Set up tasks with hard deadlines.
• If you fail your deadlines, get shot several times.
