Don’t be fooled by the calendar. There are only as many days in the year as you make use of. One man gets only a week’s value out of a year while another man gets a full year’s value out of a week._Charles Richards
Keep the tasks limited
The key tip to time management is not to burden beyond certain limits. Always keep the tasks limited. So with people working for 8-9 hours, having to travel and do things like reading, writing occupies time. So keep the tasks limited for that particular day.
When to plan?
Some say to plan ahead as it saves time. I say, plan ahead and plan on that particular day too. Have a general plan of what has to be done on that day. For example, my planner has the following: Monday; Reading books, Meditation; Tuesday: Workout, Guitar; Wednesday: Affirmations, reading, writing and so on. And when it comes to Monday, I prioritize the tasks at hand with the office work for that day.
On that day
On that particular day, I decide what has to be done and when it has to be done. For example, I use my smart band to set reminders for the tasks set for today. You can use phone alarm or app reminders whichever works for you. In this way, we don't have to remember every detail and at the same time we cannot miss out our tasks.
This time, like all times, is a very good one, if we but know what to do with it._Ralph Waldo Emerson
Use your weekends
We have a lot of time available on weekends. We can prioritize the task which demands more time. Like learning a new skill.
Take time off daily and weekly
Spend a few hours of the weekend for yourself, Just rest and chill. Take one hour a day or 2-3 hours every 3 days. Follow whichever works well for you.
Reward yourself
As the saying goes, "An effort that is appreciated, gets repeated", motivate yourself with gifts, time offs and anything you like. This acts as a booster to keep in track of our tasks, hobbies etc.
Personal note: For people think it is impossible, I work for 8 hours, read every day for 2 hours, write in a journal, doing personal research on two topics, meditate, workout. (I don't mean to boast here, If it is possible for me, then it is possible for everyone, of course, the scale varies. But it is possible). The above-mentioned content is derived from my personal experience. So I apologize if it doesn't fall under the usual time management norms.
