I believe traveling improves you as an individual, it increases your awareness and helps you learn to adapt and improvise.
To all of you I ask - how many places have you traveled? And do you have a mantra to be followed on those trips? (please comment)
Below is what I have been doing and I look forward to hearing your style.
Don't mess with the clock
Recheck the timing of your flights/transportation one last time and set a reminder on your phone. Don't go by your memory, make sure that you see the timings of the next flight one more time and set a reminder. Then reach airport/train station/bus stand early. I have had bad dreams of missing my flight. Don't let it become a reality. Also pay attention to the difference in the time zones while looking at the clock.
