Grammar Notes

Positive or positively? Positive is the adjective: “a positive attitude.” Positively is the adverb: “She spoke positively about the plan.” Do not swap them.
Positive about, not positive of. The usual pattern is “positive about the future,” not “positive of the future.”
Certain needs a basis. Certain sounds strongest when facts support it. If you only feel hopeful, optimistic is more honest than certain.
Favorable is American spelling. In American English, write favorable. British English uses favourable, but this guide uses the American form throughout.
