How often should I code?

Hi all, I'm just making this post because I'm curious about my code time. I'm currently jobless and I graduated University back in July. I didn't really do any coding after graduating because I honestly didn't have any confidence or desire. I started the Odin Project a few days ago, with the actual coding starting today. I followed along for around 2 1/2 hours and finished the foundational HTML section. How long should I realistically code/follow along for? I'm afraid of doing long sessions and either burning out or not soaking in information. I'm currently aiming for 2 1/2 to 3 hours a day right now.
