Does anyone else struggle with the 'ghaf' (ق) and 'gheyn' (غ) sounds?

I’ve been recording myself every day and listening back, but I feel like I’m just guessing when it comes to these two sounds. My pronunciation is decent, but this specific hurdle is making me self-conscious about speaking in public. Are there any specific audio-heavy techniques to train my ear, or should I just accept that I'll have an 'accent' for a while? I am asking specifically about learning Persian, not a generic study routine.
