Moving out and living on your own is certainly a big next step in your life, but very exciting! I'd say there's certainly some key things to prepare for when moving out. See below:
1) Grocery shopping and cooking for yourself: Before living on my own, I never had to shop or cook my food! Getting a few basic recipes nailed down beforehand would be a good start so you have some ideas of what to make for yourself to maintain a healthy diet!
2) Being on your own schedule: I used to have my parents help wake me up for bed or drive me to practice and so on, but living under your own roof means that's no longer the case. It's important to keep a schedule for yourself and ensure you have the appropriate alarms / meeting notices set! Agenda books work super well for me!
