This quote is stressing the importance of being able to focus our thoughts successfully. When we are unable to do this, our ideas can end up being scattered and miscellaneous, and can end up being fixated on unfavorable ideas, such as poisonous relationships and scenarios from the past.

It is important to be able to recognize when our thoughts are becoming spread and to take steps to refocus our ideas on more positive and efficient concepts. This can be done through mindfulness, meditation, and other relaxation methods.
