When we were in school, the holiday season always brought some sort of closure and growth - old books were discarded, new uniforms were stitched. Classrooms changed, teachers changed, friends changed.
But once you start a job, life becomes one long story with no breaks. Each day is like the net, and there is very little in terms of change, very little to distinguish one phase of life from another.
Which is why it is important to create moments. Plan for holidays. Plan something, and then live those moments greedily. Blog about it, take pictures, share the experiences. Unless you consciously do that, life will quickly pass you by!
