Pursuing a dream is wider than the generations past. Easier access to information and many new areas give us ample room for movement. While the progress of the times also makes the mind also more open.
We are probably a generation who are interested in risk. If the previous generation can survive somewhere until the decades, we can suddenly just decide to go because we feel what we have been so far is not what we want. Then with the spirit of pursuing a real dream, we sacrifice many things, ranging from leaving the job to spend big capital.
We must have a dream to live directed. And dreams must be pursued. But there are times when what we call a dream is a momentary desire. Therefore, before actually stepping on, preview your dreams. Is that really what you want? Do you really know where you're headed?
