The Pomodoro method really is great, but it isn't the end all be all when it comes to time management. One of the important aspects of the Pomodoro method is that there is a clear start and stop time of your task. Another way that I like to use this methodology is with an app called brain.fm. It allows you to play brain wave music to help stimulate your productivity. That alone is good enough, but it also gives you a timer. Just focus on your task until the timer ends and the music stops. 30 minutes or an hour goes by in a flash when you're hyper-focused on a task. Give it a try and let me know what you think!
I found “Biological Prime time” method works best for me, allocating time blocks for tasks and prioritising the tasks from the day before.
Your Biological Prime Time is the time of day when you have the highest energy levels, so you're most likely to be productive with your work. Mine is before 12pm. I put my phone on DND and do most of my tasks from 7-12, leaving my afternoons for phone calls and meetings.
