Give yourself a time buffer

You may think you are all set entering an address into Google maps and following their transit instructions to a T. But the thing is, Google maps wants you to be late. They will give you trip estimate that is more optimistic than the half hour you allowed yourself to get ready this morning. Depending on the trip length and the time, always add on 15 minutes to a half hour to the timing that any app provides you with if you really want to reach your destination on time.
