It is extremely important, during the first 100 rides for a young horse, that you do not apply steady pressure to the reins.  Do not hold a short rein, do not make a steady pull on the reins.  Anything that restricts unschooled horses tends to frighten them.  You do not want to create fear in the horse.  Ride with as loose a rein as you can, tipping the nose into the direction of travel by making "bumps" on the rein followed by an immedate release.  If the horse tips the nose with the first bump, release and praise.  If it takes several bumps, release after each bump and praise.  It is the release which teaches...not the bump.  Use your legs with gentle pressure to "push" the horse as a means of asking him to follow his nose.
