Look at this time management matrix and be aware of where you are spending the majority of your time.
People who are not good at time management, tend to spend most of their time in boxes 1 and 3 leaving important work until a deadline is upon them and the task becomes urgent. This leads to overwhelm and any spare time is typically spent in box 4, which comprises only aimless and non-productive activities.
Aim to spend the majority of your time in box 2, which is the most critical area for success, development and proactive self-determination.
