That's a great point. I've been playing for 15 years and I feel like im constantly learning. That is one of the huge reasons why i've taken to these forums so much. There is a ton of knowledge out there and we only know what we know. To hear different strategies from different players.... asking what they would do in specific spots. Its super beneficial and can really help you elevate your play.
Enjoy that feeling and remind yourself constantly you can only get better. Never get comfortable and think " wow I really got it figured out " The poker Gods will come running to put you back into place
