We need to be light to walk.  It is so important to learn how to leave unnecessary things behind.  Sometimes what was useful for a period of our journey and we don’t need it anymore, it can be useful to support someone else’s journey.  Try to evaluate what you really need in your “backpack”, the lighter it is, the easier your journey will be.  How good it is to have easy access to the things we need, if we have so many unnecessary things among them it is difficult to find the right one.  Light and effective should be our goal as we prepare for our journey.
