I like metrics. I use it on daily basis - to measure the progress of project deliverable, to measure performance of my group, to check new hire progress, to monitor people churn, to check software defects, to check my how my mutual fund is progressing, and so many things. I use it to check parameters on my continuous improvements. But I still don't know how to measure myself - my life. If you love metrics and know how to measure life, please pass it it along.
