Have someone else take him out so he gets used to being hacked. If he's stabled a lot he may get over-excited when he hits grass. Lead him out so he gets used to the surroundings and you can really take a good look at the route and get used to it with him.

Keep up with the lessons, try a different instructor though if you don't think you were improving. I started having lessons again a year ago and didn't think I was getting anywhere, but when I look back I am vastly improved - my seat is better, my legs are stiller, I have greater finesse with my aids. You may lack self confidence so have a good chat with an instructor to work out what your problems are and what you want to achieve before you start.

If he pulls on the reins, don't just pull back. Horses are infinitely stronger than we are and if they are given something to pull against then they will. School him in a light contact and work on using your seat and legs to slow him rather than relying on yuor hands. When he's listening to  you in the school go out and apply the same tactics. If he pulls, hold with one rein and give little tugs with the other, half-halting basically. If he doesn't respond then tug harder. If you're nervous and he's picking up on it he may not be listening to you which is why he gets faster. You need to get his attention back and that may well have to come in the form of a bloody good yank on his mouth. If he won't slow then get off and carry on leading him. Do not get off and go home or relenet and turn him back otherwise he'll learn that as a really bad habit. Keep going where you were planning to go, then get back on when he's calmer.

Ride out with someone else, preferably on a calm horse so your horse has sensible company. Keep trying, have some confidence building lessons, and focus on the positive instead of the negative. Instead of thinking 'oh, he won't stop, what if....?', think 'well, he was a very good boy cos he stood still when I mounted'. Riding is meant to be fun, make sure you work on achieving this.

You should try to walk with him (just with the bridel) and walk beside him(when your going for a hack)instead of riding.

Everytime he starts pulling make him stand still.

Everytime he does stand till, praise him.

A horse its brain works in black&white->good&bad  if you can show him wats good and bad from the ground, you will be able to do the same when you ride.

From the ground you have more dominance, so start working with him from there first.

and since your a little nervous yourself, it will make him nervous too, so when you work with him on the ground try to control your nervousness.

How are things so far? :)

lunging can just make him worse in my experience if he a fizzy type eps if a tb you wont wear them out they will run all day on adrenelin and it will just make them fitter, for a fizzy horse you need to slow them down (well ob lol) and calm them down, get respect at home by doing alot of in hand work, leading from the field and to the stable make the horse stop when you do so he is waiting for your command, make him back up a few steps, walk forward again and stop again, dont pull on his head coller but a quick sharp tug to get listerning if he is not stopping when you are.

Long line dont lunge, in my experience lunging just fizzes them up, use too lines and just get them listerning and turning, stopping and starting, Go though round and over poles get him thinking rather then wanting to go every where 100mph

When out hacking have a contact but not a tight grip to stop him going forwards, if he tries to rush, jog or canter off tunr him in a circle or walk back up the road, if you can stop and make him stand still (if you can if they are fizzy they tend to go mad if you make then stand still but it will come later on)

in the field he is bucking because he wants to go and he cant, evrytime before he bucks turn him quickly in a tight circle and at all time just walk him across grass until he learns manners,

it sounds like alot but if you want a nice horsey you have to put the work in!!! all my horses have been ex race horses 4 to 6 year olds and most would canter down the road sideways when I got them but this is what I did with them and they would walk nicely down the road on a long rein it didnt happen straight away but it will happen will rotine and education :-)
