Enter something you would like to see in a different language: a phrase you want to say, something you read but don't quite understand, a greeting, or anything else. Other Fixoodlers will translate it.
hmmm, my translation I posted the day before yesterday is missing. ???
Anyway, your translation sounds good. As another suggestion, you can say 壁にぶつかることもある。これ以上進歩するとは思えない。
