Insanely hard

EXTREMELY HARD

By comparing these two, "insanely hard" takes up less space than "EXTREMELY HARD", but they two have similar impressions to readers. Some phones may have capitalized words occupying a lot of space, so it is unwise to have all words capitalized. Also, it will look quite naive and immature if the letters are also capitalized.
