"Why should we think upon things that are lovely? Because thinking determines life. It is a common habit to blame life upon the environment. Environment modifies life but does not govern life. The soul is stronger than its surroundings"

This quote by William James is emphasizing the importance of thinking favorably. He suggests that our thoughts have a powerful impact on our lives, and that we should focus on things that are beautiful. He argues that our environment can form our lives, however it does not control them. Rather, he believes that our soul is more powerful than our environment, and that our thoughts can assist us to get rid of any challenges we might deal with. By believing favorably, we can develop a life that has lots of joy and appeal. Therefore, it is important to focus on things that are beautiful and to believe positively in order to produce a life that has lots of pleasure and beauty.
