Whats the big secret?

Yep its all about how efficient you can be. I used to check my own xp per hour and always check skill guides. Youtube helps a lot with learning about how others train efficiently. Setting goals - daily, hourly, weekly, whatever really helps. Know that youre likely to burn out if you push TOO hard though. I suggest keeping a G&A here on the forums so we can help push you and acknowledge your accomplishments too
