Which grandmaster games i should study


If your serious about becoming good follow the steps of Fischer, Kasparov, and other legendary players they all studied: CAPABLANCA GAMES, especially his 100 best games those games if studied well teach you everything you need to know to play chess well; Bobby Fischer studied all of Capablanca's games!!
At the beginning, from a rating of 0 to around 1400-something Elo, I had an aggressive style, similar to Tal. Then I met strong players from my social circle, and I switched to a more solid style — transitioning from 1.e4 to 1.d4. Later, another friend suggested I return to 1.e4 and stick with the aggressive approach.
However, I was hesitant because I had been playing solidly for so long, and I became afraid to take risks. This ultimately led to a confused, mixed-up style. I'm basically hesitant and afraid to attack.
What style — and specifically which grandmasters' games — should I follow?
Thanks for any help.
And kindly i need assistance from higher rated guys thanks atleast higher rated than me
