Well, you need to sort things out for yourself. But loving God includes worshipping him with his people, so finding a community of people who gather in his name would be a good way to start.

I was wondering - if my purpose in life is to "love God with all my heart, soul, mind and strength" then what is the best way to do this as a cab driver in New York City or as a steelworker in Pittsburgh or as a farmer in Idaho?
