Como dizer "Eu estou gostando de voltar a estudar" em inglês

Here some more. I know there still more ways to express that.
Here you go:

"I catch myself with that liking to study English again."
"I feel like studying again/I fell the joy of studying English again/I took up studying again and I happy for it/for that."
"I am falling in love again with studying English/I fell in love again with studying English."
"I am into studying English a second time/one more time, it´s my thing again!"

Yada yada yada...

As those sentences could do without the word "English" (in the case you mean just the action of "studying") I italicized the word "English". It could be also replaced by other kind of studies: studying art/painting, philosophy, etc...
