When to add some varieties?I am sure nobody likes to have the same food every day and that's why prepare various dishes to keep their taste buds happy. The choices do vary and everyone doesn't like the same thing. Not only food but it is also applicable to every action. You will be bored doing the same thing every day and that's why people take a break from their work and do something different. The same is applicable to listening to music and people add some variety from time to time. Now the interesting thing is when to add the variety? Is it possible to add the variety regularly or there is a time frame to add some varieties? Well, when you are posting a thread regularly I am sure you are not writing on the same topic and choosing various topics under the sun daily, though some topics may be repeated unknowingly.
I feel it's all in the thought process and a combination of new things that you learn regularly. The more things you learn the more will be the inclination towards making some changes. You can say it's a kind of continuous experiment. So, keep learning and add varieties as much as you can whenever it is possible.
