best advice I can give is don't get too overconfident, as you've likely hit a lot of good variance. I went from a BR of $175 to $900 in about 7k hands at NL25 (quite a few sngs as well, but mostly NL25) and I've had massive downswings since - I've been playing much better as well. Just make sure you recognize when you run hot and when you're playing your A-game.
