beginner chess studying question

I have been studying chess quite a bit lately and I feel like I'm slowly but steadily improving. Within the last 4 months of playing mostly online chess I have increased my rating to roughly 1450. I did a lot of endgame material recently studying silmans endgame book

Lately I have been reading the amateurs mind and reassess your chess

I have been really trying to get a good grasp on positional concepts as it seems to be the best way to grow into a stronger player. My question is am I going about improving the correct way or are there other things I should be learning before I study these positional ideas. If I am on the right track then what are other good resources to use to learn how to apply these positional ideas?

Laskers books on chess are to be recommended!

Sounds good shadow. What was your main method of learning then without reading books?
