Too weak

So I was playing some poker today and had built my stack up from €500 to slightly over €1k, as I was running smoothly. Then I got involved in a humungous pot with KK on a QJ4 flop. I ignored some pretty clear warning signs and ended up getting all-in on the turn, which was a 6. The pot was around €2200 and I lost it to Q4s. Though my opponent's play is questionable, it's really my own fault for building such a huge pot with just one pair. He took my stack, but from the way I played, I guess I didn't even deserve to have it. This is a big, expensive lesson, and this time it better stick!

One thing I really need to work on is to evaluate more signs and facts while I am in a hand. Playing online, I can come to a conclusion of what my line should be pretty quickly when it is my turn. I really need to start to take some more time and evaluate the hand more before I decide what the optimal play is. It's one thing to get a nasty river suckout, but it's another thing to get all your money in as a clear underdog. If I had taken some more time and seen that it just isn't worth it, I may have even been able to get off my hand. This all reminds me very heavily of this pot.

So this one is for me: Take your time, think about what exactly happened, think about what could possibly happen based on each action available, then decide on what the best play is. If the price is wrong, don't be too weak to fold a hand!
