ないと attached to a verb


I know that 頑張らないと would mean "I have to work hard" (as if I am **forced** to
work hard). What if I see someone (my friend) working hard and I am
**motivated** to work hard too. In this case, would 頑張らないと or 頑張らなくちゃ be ok?
Or is there a better phrase? 頑張らなくちゃ sounds very forced to me.




I guess in the context you describe

> 私も頑張らなくちゃ  
>  私も頑張らないと

would work fine, because it's understood that you are "forcing" yourself to
work, which is just one way to express your own motivation.

But you could just as well use

> 私も頑張るぞ  
>  私も頑張ろう

(Here 私 is just a place holder for a context-appropriate personal pronoun, for
example 僕 or こっち could also work.)
