How do I stay calm and help my horse when he is all hyper and full of spring fever ?

It may sound silly but just smile as smiling is a block to your nerves. I also sometimes sing I find this helps.
this would calm him but make sure you are calm too
usually you can first do some groundwork with him to get him more flexible and calm , gets all that hyperactivity out and after that when you feel his more calm you ride him as you normally would and you make sure he gets plenty of exercise without tiring him so much ( a bit of canter , trot , etc )
