Langclass

It's normal to make mistakes. Just learn from them. You could say something like "I made a mistake at work today, but I'm determined not to let it happen again.".Try to stay positive and keep practicing. If you need more tips, feel free to ask me.
Here’s a corrected and more natural version of your sentence:
"Oh, I feel a little sad because I made a mistake at work, and I’m not sure how to fix the motion lighting."
Tips for improvement:
1. Tense consistency – "I make" → "I made" (past tense for a completed mistake).
2. Clarity – "how to light the motion up" is unclear. If you mean motion lighting (like in a presentation or design), say "how to fix the motion lighting" or "how to adjust the motion effects".
3. Flow – Adding "and I’m not sure" makes it sound more natural than just listing two problems.
Alternative (more casual):
"I’m a bit upset because I messed up at work—specifically with the motion lighting, and I don’t know how to fix it."
Keep practicing, and your English will keep improving naturally. 😊 Keep sentences simple but clear.
