A lot of us tend to forget that sometimes, you need to take a minute and relax your mind and body. Nowadays, people are typically so busy that they barely have time to even sleep (Seriously, some people get a total of 4-7 hours of sleep over the course of 2 days). Not only is that awful for your body, but your mind is also negatively affected. Society has shifted to where getting pretty much no sleep and working endlessly is the norm.
Even though many people struggle with time management, little changes over time can have a longer lasting positive effect on the mind and body. It sounds slightly silly and a little obvious, but we all need to slow down when things seem to not be going our way, or when we feel "out of it". Taking a moment to reevaluate what you're doing and how you're doing it could really help with getting things done more efficiently.
