I'm trying to say sentences like "I can accomplish (a) by doing (b)." in Japanese, and I can't seem to figure it out.
An example sentence would be "I can earn good grades by studying hard."
Maybe the english example wasn't quite right. I know accomplish complicates the question but I do feel thats what I'm looking for. Maybe this example of what I'm looking for will help.
"I can show initiative by working hard."
Or if someone was presenting a product demonstration before an audience.
"I can make this product appeal to the audience." "I just need to show its usefulness."
What I want to construct is more "i can make this product appeal to the audience by showing its usefulness."
I'm not necessarily looking for a direct translation of these sentences. An example of how to construct the idea or something similar would work.
