Yes spend some time grooming and "cuddling" with it everyday x)
When you ride, you can trot and try to get him to bend , make circles all the time, never go straight out, not untill you can get him to bend and keep his head position without moving out of the position.
When you feel like you can control him in trot smoothly, you can try cantering, again stay in circles (:
If you do the correct things in how to bend a horse, it should only take half an hour the first time (depending on the horse). Then he should bend for you everyday in the first 5 min or so.
Also, circles help you control the speed.
I usually ride to music because it helps me keep the beat xD
That way its easier to get the horse to go to the rhythm.
When you've pretty much got him to bend and ride calmly, then you can try out some excercises, go out of the circle and if he lifts his head, bend him into a circle straight away, get him to go down then try again and so on.
Same in cantering.
And as I said before, try doing some excersises where he has to cross his feet, unfortunately I can't remember what these excersises are called in english right now.
You can also ride over some poles!
Just a few poles on the ground which you can walk, tror and canter over.
You can also try laying them out in a circle, so you're riding over the poles while you're riding in a circle.
Then maybe in the last 2 weeks you can try a few small jumps or something :)
"When I bestride him, I soar, I am a hawk: he trots the air; the earth sings when he touches it; the basest horn of his hoof is more musical than the pipe of Hermes." -Shakespeare
