Day 80 - Self Discipline is Key and I suck at it

I've been listening to this "self discipline" book at bed time each night for the last two days and it got me thinking a lot about discipline and how I can do better. I really don't feel like a super "disciplined" person but others would describe me as such. I think the reasons is that i decide to identify as "the type of person who does/doesn't do xyz" instead of trying to force myself into acting a certain type of way.
