I have noticed an increased time spent on both my phone and computer... is this a good habit that I'm about to begin? Or should I continue to regulate the time I spend with my phone and computer.
You should not spend most of your time online. It is not good for your physical health as well as mental health.
Let's plan your time to hang out with friends, family; or do physical activities which are good for both of your physical and mental health. When your brain is fresh as effects from physical activities, you can learn and work better, more effectively and productively.
Total time you spent for a work does not decide a quality of what you finish with it.
