6. 個人經驗與觀點
「以前返第一份工嗰陣，月薪 $18,000，我以為好好。直到有一次心血來潮計吓自己嘅實際時薪——每日做 10 個鐘，每星期返 6 日，一個月返 26 日——實際時薪得 $69。嗰陣我先知道，月薪靚仔唔代表時薪靚仔。呢個工具俾你嘅，就係 用 10 秒鐘揭穿你份工嘅『真實時薪』—等你知道自己嘅時間值唔值得呢個價錢。OT 係咪值得做？扣完 MPF 仲有幾多？呢啲問題唔應該靠估，而係 靠數據。」

6. Personal Insights & Expert Advice
"Back in my first job, I thought an $18,000 monthly salary was pretty good. Until one day I calculated my actual hourly rate—10 hours a day, 6 days a week, 26 days a month—my actual hourly rate was just $69. That's when I realized: a nice monthly salary doesn't mean a nice hourly rate. This tool gives you exactly that ability to reveal your job's 'real hourly rate' in 10 seconds—so you know if your time is worth the price. Is OT worth it? How much is left after MPF? These questions shouldn't be guesses—they should be based on data."
