Here's a collection of simple Apple Scripts I've written to help me during the day
youaredoingok: this script runs every hour and tells me I am doing ok. I got the idea for this from Sam Sykes, who suggested we all need a little robot that comes in every hour and tells us we are doing ok and gives us a glass of water.
encouragement: this is an enhancement of youraredoingok - it cycles through a list of encouraging things to say
logyourmind: this is another enhancement of youraredoingok. It does two things: it either sends you a message of encouragement or it tells you to log something
You can run these scripts from the Script Editor. Or you can enter: osascript scriptx.scpt from a terminal window.
