Travel is a constant learning process. Every trip makes us a little wiser and prepares for better travel next time.
For instance, in my learning curve, I have graduated to a backpack or a small size bag from a medium-sized bag, but sometimes it still becomes very difficult to travel with only carry-on luggage. I know its not impossible and many people are already doing it, and therefore I aspire to reach such level of travel-expertise some day.
But then nothing can beats one’s own experiences and learning from them. I will be sharing mine here and look forward to hearing and learning from yours.
