The life Life is that which escapes our hands when we do not take advantage of it. When we spend more time complaining, thanking everything we have. When we are more aware of the telephone, than of living in the moment, the company and the opportunity presented to us. Or when we criticize others and their lifestyle instead of bothering to live our own. I do not know if I explain, but we have no idea of ​​the time that slips away without having lived. We can be perfectly hours moving our fingers on a screen, talking about everything without talking about anything in particular, and looking at how people live their lives. The concept of living for and for us is obsolete, lost and abandoned, because we spend more time hanging around what is happening around us than what is really happening in our own lives. That is, we waste a life, a one-way ticket, and a single opportunity to do big things in doing nothing.
