Hi, 

Maybe this helps, doing puzzles and lessons etc. 

But that is member only as well puzzles and lessons etc are all member only.

You can use Lichess

Yes

Lilchess has puzzles?

I'm mostly focused on tactics but I do have fun studying everything else.

yes it does for free

chesstempo has free tactics training too. It'll give u a rating as well so u can measure ur progress. 

i'm a really agressive player sometimes!

You improve your rating by winning games. In order to do so. You have to practice, as well as playing many games

read books, practice tactics and go to tournaments.

in my experience, memorizing opening is the least effective way you can approach chess. i talk from experience
