Learning something new is difficult. Often the benefits do not outweigh the effort.
Improving your ability with something you already know leads to higher levels of skill. This higher level of skill in something you already know can lead to greater #productivity and easy-of-use than would be possible with the same level of effort investing in a new product or system.
It is best to stick with what you already have and use your energy to get better at what you already know.
Only learn somethig new if you have to or if the effort truly will be outweighed by the benefit you are likely to receive.
