Hi mate.
In my opinion, the most important thing is to decide what will be your approach to poker in the next 2 to 5 years. Do you want to become a pro or just to play part time and for fun? Your expectations should be in line with the amount of effort (and money) you are willing to invest.
After that you have to decide which poker format is the one you want to specialise (live or online, nlh or plo, cash, spins, mtts, sngs, etc). You should become extremely good in one format if you are interested in making some serious money from poker. After that you can start mixing your knowledge with other types of poker.
In my case, the learning curve (after the first years when I was playing just for fun) started from some books, then I decided that I am interested in specialising in spins, so I bought some video packages specifically for this format (and HU sng which is extremely relevant) and after that I did some coaching sessions.
If your chosen format is spin n go poker I could share with you more details. Let me know if you are interested. Good luck!
Cheers
