What do you do when waiting for server to startup?

As a beginner java backend web developer doing small projects, I find it very annoying to restart my tomcat server after every 5 minutes especially because it takes about a minute to start everytime. That's about 20% of my total work hours and this adds up to a large number when considering I am working on this for about 6 hours a day.

Currently I just eat / drink some light food or go to washroom, take a little walk around the room etc. I just want to hear what you guys are doing in this time.

Thank you in advance.
