This quote by the celebrated American writer Mason Cooley seems very appropriate for travellers like myself! Just imagine! We travel here and there that feeling of not fitting the crowd just fades away when you have gained so much from the trips. We slowly are moving towards becoming the part of the global citizens!
The greatest challenge is to begin a journey. It is not easy as we are all born lazy and to get over that emotional inertia is the greatest challenge. Once that is done, one can travel to the moon if he desires.
Nature has the knowledge hidden in its simple creations. I believe that every human invention was inspired from something already existing in nature. Seek in nature the answers to your questions and be pleased with the answers that you find.
