I don^t know how do you feel about it but from time to time I like to change something in my life. Thanks to those changes I feel that I am developing and changing my lifestyle very often. I feel good thanks to this as this proves that I am learning new things all the time. That is very important in life and you probably know it. Thanks to such attitude you are able to understand life better and simply be more happy. If you were not aware of it my advice is that you try it as soon as possible. The same rule applies to business in my understanding. Let us take a simple store as an example. When you visit it very often and notice that nothing has changed in a very long time you might come to a conclusion that it is not run properly. Do you know what I mean? The owner might be lazy or simply don^t care about it. Recently I went to a store where I bought my bathroom furniture. In the store I saw a big poster showing top ten bathroom furniture of the month. As you can imagine it is changed every month and thanks to this customers not only know which bathroom furniture is popular but also see that the store is trying to upgrade itself. That is very good in my opinion.
