Time and resources are limited but 'everything that is to be done' is always unlimited, so there is bound to be a compromise, a trade-off.

Something will always be neglected or deprioritized, no matter what you do.

Humans are not a machine or a piece of equipment, that can be made to work overtime and show more productivity.

We don't work like a machine, and working more hours does not mean more actual work. If we respect our body clock and work with it, we can be more productive.

At your workplace, if it is accepted by you and declared to your peers that you are not good at doing a certain job or task, you will not be assigned that type of job. This way you can be less busy doing mundane time-consuming work.

Doing tasks too early, the opposite of procrastination is also a cause of being avoidably busy.

We end up doing trivial tasks that are not required or not that urgent, at the expense of our real work.

Some work (like answering all your emails to clear your inbox) creates more work, and while completing that work may seem like being productive, it is, in fact, adding to your workload by generating further tasks.

We live in an urgency-addicted world, fueled by technology.

While it may seem counterintuitive, it is a good idea to slow down during pressing urgencies.

Just have a 5 item limit on your daily to-do list instead of an endless and overwhelming list of work to be done, staring at you all day.

We are far too busy in ways not imagined before, though productivity hasn't increased proportionally. Studies show we have more leisure time than before but have become overwhelmed with an infinite number of options.

Reclaim your time and your sanity instead of being busy all t...

To keep complaining to others about how busy you are is useless and it makes others anxious around you.
It also shows you may not be really busy otherwise you would be working instead of talking about the work you have to do.
