Don't hesitate trial and error!! Must important thing is what you do by yourselves.

Since Information Science is a relatively new field, everybody involved in it has a huge opportunity. Both business and academic research laboratories are seeking new study results. You have a chance to research any subject you wish at graduate school. For many of you, this will be the last chance you ever have to conduct studies freely. I recommend that you increase your value to the world by producing study results before getting a job.
