Right On!
Man’s (specifically a Jew’s) purpose of creation was to serve his Creator (incidentally thereby obtaining a portion in the world to come). That is everyone’s hashkafa. The only difference in opinion is by which method, where to put the emphasis. (I don’t have access to Hebrew now (Rabbeinu Google), I think there’s a Passuk in Navi Yeshaya something to the effect “I created you Yisrael, a servant for me”.
And for that special opportunity, privilege we give thanks thrice daily in the great tefillah of Aleinu.
