There are 365 days in the Gregorian calendar and in each; there are exactly twenty-four hours. Every single day has the exact same number.
That being established, do you mind explaining why you feel that what you couldn’t achieve in a day can be achieved in the next- when they have the same number of hours and are as unpredictable as the next?
The focus should be on how to make your assigned twenty-four hours of each day count, not on making excuses and adjustments in the next day for what should have been done.
If you set out in each day, with a mindset to achieve the most you can, you would realize that twenty-four hours is enough for you to do so much that you don’t just feel productive; you actually maximize your capabilities.
Twenty four hours may never be enough time if you do not have a plan of action to guide your activities. You may end up stuck in an endless cycle of ‘too much to do, too little time to get it done.’
Just work harder at making the most of each day and pace yourself so you never lose track of where you are headed, where you are, what you’re doing, what you’ve done and what you should be doing. Before complaining about your workload, adjust your time management and improve your skills in that area. Then and only then will you realize those 24 hours are enough if you’re doing the right things at the right time with the right energy.
