Daily reading ties into the rich habit of personal and professional development. The wealthy constantly fine-tune their skills, keep up with industry developments, and learn new things. Like anything else, the type of content we consume can have a huge impact on how we grow and what sort of opportunities become available. Tom recommends focusing more on self-help, self-improvement, educational, and similar materials.
As Tom explains, the wealthy spend 30 minutes or more a day studying information related to their career or profession (perhaps new ventures they are considering as well). They do this day in and day out, like brushing their teeth. This helps them find opportunities that they may not have realized existed otherwise. Better yet, this discipline builds up your confidence and capabilities.
Remember: your habits determine your success.
