There are only 24 hours in a day, whether you’re a high-level CEO or a first-semester intern. Time management and productivity are valuable skills at any career level, but what do some of the most successful people in the business world have to say about them? Regarding productivity, it’s important to have an abundance mentality: There are enough resources and possibilities out there for everyone to thrive, and stressing about what is currently inaccessible will kill productive time. Additionally, don't be afraid of being wrong. Anyone who takes too much pride in being right all the time will miss out on learning new or better methods and techniques. Often the fastest way to progress is realizing that you’re wrong. And goal-setting activities, while also important, should be as specific as possible in order to make goals achievable.
