This quote suggests that optimism, while a positive and beneficial trait, is not productive or effective unless it is accompanied by personal effort. It means that merely having a positive outlook or expecting good outcomes is not enough to achieve success; one must also be willing to put in the necessary work and effort to realize their goals.

The state of mind referred to in the quote is the optimistic outlook or perspective, which in itself does not produce tangible results. It is only when this optimism is combined with action, when it motivates an individual to strive and work hard, that it becomes fruitful.

In essence, the quote is a call to action. It emphasizes the importance of not just dreaming and hoping for the best, but also actively working towards achieving one’s dreams. It underscores the fact that success is not a product of luck or chance, but a result of hard work and determination.

Applying this idea in today’s world, especially in the realm of personal development, it means that one should not just be content with having positive thoughts or dreams. One must also be prepared to take the necessary steps to actualize these dreams. For instance, if a person is optimistic about getting a good job, they must also be willing to acquire the necessary skills, gain the relevant experience, and put in the effort to apply for jobs and attend interviews.

Similarly, if one is hopeful about improving their physical fitness, they must also be committed to regular exercise and a healthy diet. In other words, optimism must be paired with action for it to be beneficial.

In conclusion, while optimism is an important attribute that can help to maintain motivation and perseverance, it must be complemented with personal effort in order to be truly fruitful. It’s a reminder that while positive thinking can set the stage for success, it’s the action we take that truly gets us there.
