The attack setting you use for mix buss compression is just as important as using a compressor on any other individual track. With a faster attack, the compressor will clamp down sooner on the transients that tend to be a little louder than the rest of the audio coming through. A slower attack will wait milliseconds before it clamps down on the audio and starts compressing. What I like to do personally is start my morning off by blazing through the most important tasks of my day while my energy and focus are at their peak. This may include sending time-sensitive files to a client, responding to emails, and bouncing stems for a performance. Pushing through my important tasks early gives me time to complete more creative tasks during the rest of the day, such as practicing my instrument, working on new material, and writing with collaborators.
