The phrase "let's see how far we go" is used to express the idea of exploring the extent or limits of what can be achieved or how far one can progress with a task or challenge. It implies an intention to find out the potential or outcome by moving forward and testing boundaries without knowing the ultimate result beforehand.
It is often used in situations where the exact outcome is uncertain, and there is a willingness to proceed step by step to discover how much can be accomplished. It carries a sense of curiosity and experimentation about one's capacity or the possibilities ahead.
This phrase can be used literally, such as seeing how far one can physically travel or progress, or more figuratively, such as in ambitions, projects, or relationships, where the destination is not yet clear and is to be discovered through ongoing effort.
In everyday use, it aligns with the sentiment of openness to outcomes and a willingness to proceed and find out what happens next.
