Both "in spite of..." and "always trying..." are adverbial modifiers. This is an okay sentence structure. It might be preferable to rewrite as: "In spite of..., (main core), always trying..." However, this is not strictly necessary.
Note that "always trying..." is similar to starting a modifier with just the word "trying..." The only difference is the word "always," which itself modifies "trying." When we begin a modifier after a comma with an -ing form, we are using an adverbial modifier, related to the preceding clause (and in this case, although the words immediately before this modifier are not the clause we want to modify, notice that the nearest - and only - preceding clause is the main core; thus, the meaning is unambiguous).
