Where did that beginner drive go?

It’s been 3 years now since discovering a new mentor and trading strategies. A few payouts here and there and lots of failure. I’m a little burnt out even with breaks. I used to be able to study for hours and want to grind, now it just feels like homework and I have to force myself to study. How do I get this obsession back? This drive? I want to be great but I’m weak, I’m illdisplined. But other aspects of my life I’m fine. I workout everyday, eat well, sleep well.. but I can’t fucking study trading!!
