Being underestimated gives you room to work. Use it to get good, not to get bitter.

Low expectations are uncomfortable and genuinely useful. Nobody is watching closely, so you can be bad at something for months, fail quietly and improve without anyone narrating it. People who are expected to be excellent rarely get that. The trap is spending the time proving a point in your head instead of using the quiet.

If you are overlooked right now, pick the thing you want to be good at and work where nobody is looking. Keep a private record of what improves. The day people notice, you want the work already done, not a speech ready.
