まだまだ不安定って英語でなんて言うの？

「まだまだ不安定」は英語にすると「Still not stable」になります。 質問者様のお求めのスピーチ（？）は次のようなくだりで良いと思います： - We're a new company, very young, and not yet stable, but all of us are really motivated. - We've only just started our business and our situation is still not entirely stable, but I feel that we have a bright future
