Hello Matthew!
I can share my personal experience. Well I’ll make it short. Hahah
I lost a lot of money when I started playing like most of us here, but to answer your question all I can say is don’t get married to any hand. It took me quite a while to be able to fold pocket KK and even AA. Although pocket rockets is hard to let go of even today. Watch your posture and tells in live games. Try and analyze what you did and how you could have done better.
That’s all I have for now. Hope it helps. Cheers and
Good luck!
