Like a budget hard drive after 6 months use, my memory is shot. I feel like I can barely remember anything.

I've been learning to code for the past 6 months and I have to periodically relearn all the concepts I had already learnt to implement them. I must mention that I am also trying to learn another language as well as do my full-time day job at the same time.

It feels like I am barely making any progress and that has been a shot in the arm to my confidence.

I don't want to feel like I suck at everything, the only thing I think I have going for myself is that I think I can improve myself.

Any tips to help with memory retention?
