The secret to finding fulfillment in life is different for everyone. The main hope for people is to live a long, happy life where all goals are achieved and there are no regrets.
People by nature are busy creatures. As much as we complain that we want to lie in bed all day and do nothing, there are very few people who could actually do that and find happiness. Fulfillment cannot be found by being lazy and doing nothing. However, some people, especially younger people, often find it difficult to think of something fulfilling to do.
