Three. Three is the running count of items that are currently not with me.

1. Wallet: Stored in the correct place, but I did not perform my usual check before I left the house
2. Key: Placed in a shirt pocket and not returned to its usual storage location at my work desk. The key should not have made it to my house.
3. Food item: Intended to bring for lunch. I did bring two out of three things that I intended to bring, but I am frustrated that I did not verify what I had with me before I left the house. I am easily vexed by doing things out of order, by the simple placement of items outside of normal locations, and by my internal dialog which distracts or confuses me from whatever my intended course may be.

While I did leave the house fully bathed, fully dressed, and arrived to work on-time, I still need to work on systems that result in more consistent execution.
