western pleasure you really are sitting on your pockets... you arent nearly has far back as you feel like you are... also, people tell you to put your weight in your heels but the way I can explain it is... put your heels down, don't lift your toes up, alot of people will hold their toes up, that's different from pushing your heels down, different muscles... Also when you put your weight in your stirrups, the weight should be on the inside ball of your foot, not towards the little toe... also... this is going to sound silly, but make sure you are not curling your toes....
"Be a best friend, tell the truth, and overuse I love you
Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
