Age 30, started studying chess seriously at 25 (around 1000 strength). Hope to be 2100 OTB by end of the year. 15+hours a week on avg past 5 years studying/playing. Having an OTB stronger player for guidance/coaching was important, Tactics puzzles are important, slow games are important, constantly analyzing your games is important, keeping the joy/motivation is important (I watch lots of chess videos, banter blitzes and such, chessnetwork, johnbartholomew, chessbrahs, simon williams, jan gustaffson)
You are doing the right things--on the right path.
Don't know if you are studying endgames but you should study those--especially pawn endgames.
