@Chambaru first off, not cool to use some alt account and point to a bio that doesn't exist. But if you want proper advice, look at Silman's famed "How to Reassess your Chess" at page 391f.
Citing the core point:
"if you are more interested in improving your overall understanding (rather than just gaining a few rating points due to the help of a complementary opening repertoire), then a very different opening philosophy can be implemented:
Choose openings that don 't suit your style/temperament!
Choose openings that cater to your chess weaknesses!
Choose openings that freak you out and leave you feeling vulnerable and insecure!
In other words, this system of thought recommends openings that force you
to come face to face with your chess failings so you can patch them up! [...] Be warned: This "bizarro" repertoire is only for brave souls who are extremely dedicated to improving every facet of their game, no matter how much pain and humiliation it takes for them to achieve it (and there will be pain and humiliation since you'll suffer many losses as you slowly but surely raise the level of your chess IQ)."
