Life is full of business. It will be a delicacy for many to have spare time, I know. But on the other hand, many don't know how to make their spare time productive. Well, there are some other people who would not love the idea to be productive even in our spare time.
But let me tell you that you don't have to learn 'PowerPoint' during your spare time or something you might not like. And believe me, you will not feel you are doing something productive which our brain may not like. Do you can choose anything you like. Just make sure you don't sit idle, scrolling your social media, or watch tv for hours.
Focus what interests you. It can be volunteer work, a singing class, work out, or anything. You can make a new hobby to spend your time, not necessarily it have to be a source of income. Or you can meditate, read a good book, or take care of plants. The thing is, make sure you are interested in it.
I know these also doesn't sound very productive. But you can do your own research on how these activities can passively make our life better. Not only that these can improve our creativity as well. You may have something in your mind, you wanted to do but never had the time. And if you feel too lazy to do that during free time, then you must go for it. Motivate yourself to do so. Believe me, it will add great value to your life.
Life is not about rushing one task after another. A good long bath can make you feel a lot better. Allow yourself the time to shift your mind from this busy world and do something which makes you feel better. Just sitting quietly without your phone notifications or any book or without monitor time can help achieve your calm state of mind.
Don't focus on the productivity of your time, focus on if it's quality or not. If it's adding value to your life actively or passively, embrace it!
