Thank you for your query.
Time management, according to me is a HABIT more than anything else.
I will share how I started off managing my schedule hoping it would help you understand how beneficial it is to manage time.
I used to be more adhoc in nature and everything was based on instincts and interests and was mostly into procrastination.
Then I attended a session on Time management and realized the importance of it and also understood how it would make my work and my life easy.
Few things I focused on:
1. Making a To Do list and adhering to the timelines
2. Prioritizing the work as High-Medium-Low on importance for completion
3. Scheduling my day to day activities
So based on the above points, I made a list of things I need to do daily including the basics as bath, eat, travel, etc. Everything was time based and scheduled. I practiced this and today its my habit. I follow it religiously and it has eased my work and my personal life too. I have calendarized everything I need to do and today's technology (mobiles, watches, etc.) are a big help in keeping up with your schedules. I'm able to do all of it in time and also get to have free time to have some fun.
I hope this helps you in getting better at managing time. I will you all the very best.
