Charles Du Bos - "The important thing is this: to be able at any moment to sacrifice what we are for what we could become."
Yeah. I guess this is the stumbling block in most cases wherein people have had a dream but rarely had the guts and the gumption to pursue it to its end (its materialization)....lest they lose what they already have. I have been fortunate to come across a few friends who have let go of their present and looked at a less certain future. Inspiring, to say the least.
