o no. Not the dreaded imnotgoodenoughitis!

You definitely are! You ride much better than plenty of people I see out jumping fox so not only are you good enough, you would appear to be over qualified!

He's gorgeous and you have a jumping position I would literally kill for (my toes turn out and I don't give with my hands ) so enjoy, have fun and don't put any pressure on yourself because you definitely are not going to ruin him riding like that
