Getting Better, Where to Start

I've been playing for about a year, mostly live and some online. I'm a pretty big loser online, albeit I have mostly played GGpoker high variance tournaments but that's no excuse.

I understand the fundamentals like pot odds, outs to equity, my open ranges in cash games and for short stack MTT (I play pretty turbo MTTs if I play live) as well as other basics. Sure I'm no expert at these things and I am sure I make mistakes but I'm looking to level up my game and hopefully make a profit but I don't know where to start. I'm a free member of Poker Coaching and I find their resources useful but I feel like I'm not making progress. Is it time to look at board textures, bet sizings and study my previous hands (I have some hands saved on GG and from live). I usually play pub poker games, rarely casino MTTs, online multiple thousand people entry bounty tournaments and as of very recently live 1/2 because my local casino has insanely low rake and there are huge whales and OMCs, though I am not properly bankrolled at all and don't get many weekends off due to my job

I've been looking at GTOWizard and it looks really good but some people say that it isn't aimed for people of my skill level. Is it better to use free resources or to buy something like this and study 70% play 30%? I'm about to quit online poker until I begin beating softer fields so I'll end up playing probably once a week minimum and maybe an occasional cash game or casino MTT.
