What are you planning to change from before? To reach a new destination, you must also take a new path. Some things I would suggest,

1) less tables, learn more poker and grind less
2) More buyins, try playing "overrolled" move up at 30 instead of shots.
3) forget hands and start working on tons more PT analyzing of your game.

This is what I have done since the new year, and it is working out immeasurably.
