You need to play for a long time... and even with "magic shortcuts," you have to level up a lot... and definitely keep track of the missing skills...
I advise you to immediately acquire all 5 necessary schools... and then develop the ones that are specifically needed to obtain the skill itself (usually these are 3 branches)
P.S. It would be nice to know this "automatically" so you don't have to jump from the game to the skill wheel (Alt+Tab).
