Chess improvement isn't some linear progression. Just putting in the time may or may not actually provide you with improvement from a rating perspective.
The most important thing is finding your biggest weaknesses and try to fix those, whatever they are. Even then, it may take a while for that to be reflected in your rating, if it ever does.
