I wish I could...

So many times we wish that things could be different, that at least we could turn back time and fix things or maybe enjoy little tiny moments like they were our last ones. We have so many wishes and we want, so badly to accomplish them. But the point is: Will we take advantage and do the opposite that we often do? Is it just an excuse for not saying that we are not capable of doing it? Or is it just an excuse for feeling less guilty?
