I be up in the gym just working on my fitness?

Hey y'all, i'm trying to get in better shape but i'm in school full time and work part time so I honestly don't really have the time or money to enroll in a gym. Does anyone have any quick fitness tips/tricks I can use? Maybe a quick morning/night workout routine that will give actual results? Also, I know diet is key as well. Feel free to give any suggestions?
