Common causes of laziness include a lack of energy, focusing on short-term pleasure instead of long-term consequences, and losing motivational sources. Other possible causes include an abundance of resources, genetics and even mental health disorders, such as depression, ADHD or schizophrenia.
A lack of energy can be caused by a nutritional deficiency, a change in exercise routine, sleep issues or stress. Junk food, especially when eaten consistently for long periods of time, can cause laziness. Motivation can falter when working on the same task for a long period of time, or when the task at hand no longer seems important. One reason to focus on short-term pleasures is because of the resources available in many societies. While human ancestors only considered their short-term needs because of the scarcity of resources, modern humans have many resources available to them already. The mindset of only satisfying short-term needs can cause laziness when all the necessities are already available.
One method of improving motivation is breaking down goals into smaller, more achievable parts and focusing on one thing at a time. Other motivational techniques include repeating affirmations and visualizing completed goals. Being around positive influences, such as successful, well-motivated people, helps prevent laziness.
