How much should we share about our plans - is the evil eye a real concern?

Assalamu alaykum. I’m from India and trying to figure out how real the idea of the evil eye is. In my family, girls are encouraged to study but are usually expected to marry and settle down eventually. That’s been the path for my cousin sisters and my sister‑in‑law. My situation is a bit different: my parents, especially my mum, have always supported me to study more and become independent. I graduated from a good university and for the past year I’ve been at home preparing for very competitive exams. If I pass them, I’ll get a stable and respected job. I’m doing fairly well - not perfect, but giving it my best. The problem is relatives. Whenever they visit or we visit them, the first question is, “What are you doing now?” I usually tell the truth because I don’t like hiding things. But my mum tells me not to share details. She says, “Don’t tell people what you’re doing. People’s intentions aren’t always good. Wait until you get the job, then tell everyone.” She strongly believes in the evil eye and thinks telling people about plans or progress can bring negativity, jealousy, or bad intentions. I’m torn. On one hand, I trust that Allah knows my heart and intentions, and that He is the best protector - nothing happens without His will. On the other hand, I’ve seen how comparisons, pressure, and quiet jealousy can happen in families, even if nobody says it outright. So what do you think - is my mum right? Is it wiser to keep your goals and progress private until you actually succeed?
