Hello Sister, I understand how stressful making RU-vid videos can be. The eagerness to start is so real and then as you keep creating you end up getting bored especially when you have low visibility and it feels like waste of time. Just take it as hobby and don't stress yourself. Everything will be alright.
Also, one thing you can do is you can choose not to talk. Just do the hairstyles in a joyful manner with a calming sound or music. You already have a camera beauty so you can keep quiet most of the time without doing any voice over so that people don't notice your voice is unhappy or fatigued. Okay? Just smile and do voiceless hair tutorials with a calming sound or music. Action speaks louder than words. For me when I watch hairdressing videos, I mute the background voice because I'm interested in practical braiding not the talking. So just test between voiceless and voiced tutorials which one works for you. Since you are already beautiful on camera you don't need to impress anyone. If you aren't so beautiful, you may need to attract your audience with your voice. It's a trick. Some will love you either by your beauty or voice. So to me, looking at you, you can succeed with voiceless tutorials because you are already beautiful. So don't shoot voice videos with fatigued or bored voice, if you want to talk then script it in a brief and happy manner. Just an advice from an experienced sister. All the best!!!
