There really are the days when we are doing on something very important such as school works, projects or even from our personal interest. If it's too much for a day, we cannot really finish it in one sitting, added  that there are other matters that we need to attend to. At the end of the day, we feel like we should have done more or we haven't done enough for today. 

This is what we need to stop. It's called "Productivity Shame". 
Productivity shame is the act or feeling that you've never done enough. Like no matter how many hours you work or how many tasks you cross off your to-do list, you always feel a sense of shame around your work. And even when you do make some progress on your goals, it never feels like it’s enough.

It is also the feeling that you aren’t allowed to do things that are “unproductive”. You feel a sense of guilt when you spend time on hobbies, watch a movie, or simply sit back and relax. 
Basically, you're addicted to being busy and working your ass off. 

Now, why do we need to stop this? It may appear to be hardworking and productive but apparently these are UNHEALTHY MENTALITIES we need to avoid. When you can’t celebrate your accomplishments and can’t disconnect from work, you’re leaving yourself open to stress, overwork, and eventually, burnout. 

Unfortunately, our workplace culture promotes productivity shame. We’re made to believe that being passionate and driven to work more is the only way to get ahead. But is it?

Aside from it's crushing your motivation and taking away joy from your supposedly down time, it is also a terrible way to find motivation during the workday. Think of it this way, Does feeling shame over your lack of productivity help you achieve more? Does it make you happier, more joyful, and a more productive person? Does productivity shame motivate you to get more done? 

Certainly not.

Instead, productivity shame creates a cycle of failure. You feel ashamed of not being productive enough, which causes you to be less productive, which causes more shame. If the cycle gets bad enough, it can be paralyzing. 

Rather than inspire us to be better, shame destroys our self-confidence and, in turn, our productivity, creativity and happiness.

The result is a deep sense of shame—feeling that you could always do more and that what you’ve accomplished just isn’t enough. You replay the day in your head, thinking of all the things you could have done and how you’re never going to hit your goals or live up to your expectations. It will lead then to disappointments.

In conclusion, what I just wanted to say is, stop linking your self-worth to your achievements. Be proud of any progress you're doing. Setting an unrealistic goals for yourself is not it. It won't work. And lastly, don't be stuck in the belief that everyone's doing MORE than YOU. We all have our own struggles. Just trust the process.
