It is logically inconsistent to believe in purpose without first seeing out a creator. When you see something that you consider to be well designed and well created the first question you ask is who made it the next question is why was it made?
1. Your life has Value: Your life is valuable because it is valuable to God - not because you're rich or poor not because of your skills but because you were born and created by the most high God, your life is valuable already.
2. Purpose is not unique: if God created all men the same way, then he created all men for the same thing.
3. Purpose is not talent: Many times talent require circumstances to be unlocked while some other talents we have may not be useful.
Another thing we don't judge purpose by is if it is making us money. If the creator created you for a purpose then your purpose must matter to him first.
