All software is change

The cliché says that there are only two certainties in life: death and taxes. 

There's a third: Change. 

It will happen. You can't stop it.

Change is anything new or different. This is core to what a software developer does. A new product, a new feature, and even a bug fix, will all involve changes for the person using the software.

Software developers are also well known for wanting to use the latest product, the newest framework, or the toolset currently being hyped on social media. All these new things will involve changes in what they do and how they do it.

Resistance to change is a natural response amongst most people. Or, to be more precise, unwanted change is resisted by most people. A positive change without the need for a lot of effort or disruption is normally welcomed.

When something changes, you may have to learn how to use the new version. There may be a negative consequence due to the time taken to learn the differences, but these will hopefully be outweighed by the benefits the change provides.

Very little software is written once, used, and then discarded. It's far more common for software to be developed over a period of time and for changes to be made to it once people start using it.

If you're involved in creating software, getting used to, and accepting, change is something that will benefit you in your career.
