"我父亲告诉我，一开始就定好你的价格。"

Simplified Meaning:

The quote is about knowing what you're worth and setting your standards from the start. Imagine you're looking for a job. If you ask for the salary you believe you deserve right at the interview, it shows confidence and helps avoid any misunderstandings later. It's like when you go to a market: if the seller puts a price tag on something, you know immediately how much it costs and can decide if you want to buy it. For example, a famous artist might say how much they charge for their work before they start painting, so everyone knows the deal from the get-go. This advice helps people avoid feeling undervalued or cheated because everything is clear from the beginning. It's a way to make sure you are respected and treated fairly in any agreement or relationship.
