There just does not seem to be enough time in the day to get everything done that needs to be done. Or is there? Maybe, you need more time to get more accomplished because of how you spend your time. Think about all the things you do in the day, both at work and at home. Can you eradicate or curtail anything? I suspect so. But more often than not, we convince ourselves that we are already operating at full capacity.
Instead of complaining about needing more hours in the day, start believing that you can do more. Capacity is a state of mind. Convince yourself that you can do more, and your mind will find ways to make it happen. More importantly, convince yourself that you should do more, and stick to your conviction. Eliminate your distractions – unmotivated coworkers, checking social media, etc. – and get more done.
