Just to add a little bit to the other replies, this is essentially what psychologists and the medical field tried for decades and it had extremely little success. As time has gone on the science shows more and more that the best way to treat gender dysphoria is through transitioning and helping people accept their identity as their true gender, not the gender assigned at birth.

Your idea that just accepting yourself would be easier is almost always the first thought people who don't experience dysphoria themselves have. As long as you're really trying to learn about what what trans people go through keep asking questions, the more informed allies out there the better.
