Here is a simple strategy:
The solution is to work your time backwards.
For example, start to calculate the time you need to reach your
destination not starting from your home but from the destination
itself. You could try writing it down until you become comfortable
with such a mental chart.
The chart could look like this:
Time needed to reach the office in the elevator: 1 minute
Time needed to park car and get to the ground floor elevator:
Time needed to find parking space: 5 minutes
Time needed to drive to office from home: 20 minutes
Time needed to reach car park from apartment: 3 minutes
Time needed to lock apartment: 1 minute
Time needed to dress and get ready: 15 minutes
Time needed in bathroom/shower: 15 minutes
Now you just have to add up these figures and you will get an
exact idea of how long it takes you to get to office.
Remember to calculate in time for unforeseen events. It would be
a god thing for example to anticipate a traffic jam and give your
self some grace time for that.
Similarly finding a parking space can sometimes prove to be more
trickier than a treasure hunt. So you could give yourself a couple
of minutes extra time here and there if such activities are involved.
These values are purely an estimate, they vary of course from person
If you work backwards like this, you can get a very accurate idea
of how long you will need for something.
Then how can you possibly go wrong?
