This is a personal question that cannot really be answered by someone else...
Think about new tools/softwares you have picked up over the past years whether it be as simple as Microsoft Word or Excel, or more advanced technologies such as programming languages, DBMS, or operating system tools such as task scheduler to automate things.
Personally, I have started using software to help develop and deploy software while collaborating with teams such as Git, Jira, GitHub/Bitbucket, and Bamboo. I have also become more proficient in Python and learned more about full stack development in JavaScript.
Again, depending on your personal experiences and the context of the question, this answer will vary.
