I haven't read any other replies, but I can imagine that they'll read somewhat like mine.

You're playing way too loose. You need to start to play a tight/aggressive game of NLHE. In general, tight is right. Whoever gave the idea of raising with any cards ten or higher doesn't know what they're talking about. For the most part hands like KQ, KJ, KT, QJ, QT, etc. are trap hands when in an early position. Some of the better ones become playable in a late position.

The important thing is that you have to learn to play tight. You want to play loose? That's fine, but you must understand tight/aggressive play first, develop some serious hand reading skills, and be prepared to lose. Don't jump into loose/aggressive play. To quote a famous movie, "First land stand, then learn fly. Nature's rules, not mine."
