An Empty Glass

I always thought that being empty is a negative feeling. But then, when we try to realize and observe the things going on around us, somehow, we can compare ourselves to an empty glass. This is because every now and then, we have to be filled up with knowledge, with experiences, with lessons, and with emotions as we struggle in this world everyday. If we will compare ourselves to filled up glasses, then, we can no longer absorb the new experiences we gain, and never learn from them.
