Give each task your undivided attention to increase your productivity and quality of work

Remove sources of distraction.
Noise, music, phone calls, text messages, and so on are all major sources of distraction. Find a place free of these distractions, such as a library or a co-working space. Work on your assignments and projects in your chosen place with your phone turned off.

Separate each task so that they do not interfere with each other.
Keep your tasks as separate from each other as possible. For example, proofreading is an important part of writing a manuscript, but different skills are involved. First, write your manuscript with the mindset of a writer, then proofread it with the eyes of a critic.
