The biggest problem I have noticed with mature age students is their mental approach to the training. There is no noticeable difference in reflex, coordination etc but there can be a huge gap in the ability to learn thoroughly. Half the time I don't even think that the mature aged student realises what they are doing to hinder their learning capability in this environment. If you have succeeded in another industry/career than you have the right to possess the confidence and satisfaction of achievement and have faith in your own ability. This is by no means a go at you guys, just a bit of advice. Leave everything else you have ever done on the ground and you will learn more efficiently and become a better pilot for it.
The best students are those who think they will never be able to hover at the start.
