Getting started as a makeup artist - tips please

Hi all, I’m hoping some experienced makeup artists can help me out.

I have researched on how to get started and it always suggests using friends and family as practice.

How do I go about that with a full time job and everyone having a busy schedule? Ppl say they will support by helping me practice but how do I ensure that it happens??

Also, how often should I be practicing and for how long? (Practicing on myself for almost 10 years)

Don’t hesitate to share any other tips please!
