People explore places by using boats and going out into the sea or ocean for long periods of time. Others could also do another type of exploring. For example the exploration of cancer cells and trying to find the cure for Cancer.

Individuals have devoted themselves to a life of exploration and discovery because there is so much out in the world that is still unknown. There is also much more that could be discovered. Some people may set goals to make a difference in peoples lives and they can do this by making a new discovery and being able to say that they change the lives of others and be proud of what they have done.

The sacrifices that are made by these individuals could be leaving their family for long periods of time. Also they could try to do or find something for months, or even years and not find what the were searching for.
