So far I am doing good. I am level 12 and I have made the top 1000 list of both achievements and places visited according to the Leaderboard. However, I am back in the thousands in terms of XP. Now, I am not XP obsessed, but unless I am significantly gaining achievements faster than other people, then these people ahead of me must've gained XP faster than I have. Out of curiosity, I'm wondering, what are these people doing to level up faster than I am?
