I think the word "inspire" is not correctly used in your sentence "Stay positive and inspire."
The meaning you want to say is in the transitive form of "inspire". However, you use it in an intransitive form which means "inhale". So your sentence means that "stay positive and inhale", which is obviously not what you wanted to say.
What redneck says makes sense except that I'm not sure that is the meaning you wanted in the first place, because "stay inspired" is to be open to get influenced by others. It appears that what you really want to say is to influence others, which is literally opposite of the meaning of "be inspired".
However, it feels like what redneck really wants to tell you is that it is good to be positive, and it is even better to be both positive and ready to be in other persons' shoe.
