A great way to stay on top of what you need to do and when you need to do it is to connect your Google Calendar account with your cell phone.  Then you can have Google send you text messages to remind you of when you need to do stuff.

To get started, just provide Google Calendar with your cell phone number, then select the carrier.  You’ll get a text with a code.  Then just enter that into Google Calendar and you’re good to go.

Makes it easy to stay on top of your schedule, particularly when you’re out and about.
