don't feel bad, the flare is pretty much the hardest thing you'll learn to do.
That is SO TRUE and bear in mind that even dozens (hundreds!?) of hours after you get your PPL, this will still flummox you on occasion! For example, if it's been a while since I've landed on a very wide (e.g. MIL) runway, I find that I misjudge it. But overall it's a bit like riding a bike... you just have to do it again and again and again until it "works".
