Life In 19x19

Did I resign too early? I read a lot into the the game and I was going to lose by a large margin. Was I right or wrong?

Resigning might be ok here, but I don't think there's a problem with trying an invasion at the top first.

Some other thoughts:

I think was bad. You have enough room still to approach at F17.

and crawling along the second line is bad, because white gets a nice wall. Play D18 to take the corner.

and feel small, pushing up against a weak group. I'd go straight for K17 or therabouts.

: It's not too late for an invasion, try to keep white from getting so much on top.

Most important advice: Play lots more games!

crawling on the 2nd line, any more, in this situation, is bad.
As emeraldemon said, joseki is D18 hane. Study this common joseki.

Without looking at the game, I can say yes, it was too early to resign. I'm only half-joking. In even games at your level, don't resign. If your opponent killed a 40-stone group, keep playing until they are captured and off the board. Your opponent is perfectly capable of making a mistake larger than yours. This is especially true in tournament games--there are so many enormous point swings at the kyu level.

Of course, there are limits to this--don't play just to win on time, etc. Also, don't wait long to resign in teaching games (that is, against players much stronger than you).
