Time tracking, ticket management, email. How do you stay organized?

I've been trying to think about ways to improve my organizational habits lately and so I thought, what better resource than r/sysadmin?

Let's talk about ticketing systems, time trackers, & to do lists!

1.) Do you use helpdesk software, if so, which one? & Which one would you rather be using? 2.) How do you keep track of what you've been doing all day? 3.) How many emails do you get a day, and how do you manage them? 4.) Alerts. Ugh.
