If it helps, my BR is now well over $3k and I am only just dabbling in $50NL and $100NL, as I feel my game hasn't been solid enough up to this point to make a real and successful attempt at the higher limits.

Don't allow yourself to feel the pressure to move up when you're not *truly* ready for it, as it will just be another negative emotion waiting to wreck your game, and your enjoyment of the game, if it gets half a chance.
