I was young and naive. I didn't have the advice I have now and made mistakes. I didn't understand it was about attitude as well as ability.

I'll keep going. That's one thing about myself - I'll roll my sleeves up and keep going.

It really hurt me when there was this perception that I didn't want to play for Scotland. I was fuming, absolutely gutted.

People have questioned my commitment to Scotland but it's actually the opposite. My problem is I can never say no.

It has never been about me. That's not the way I am. With Scotland, it has always been about the squad, the lads who were trying to get some big results to start the Euro 2020 campaign, rather than lads who were away from it, who people didn't know the truth about.

When I had other things to deal with in my personal life, people were telling me to come and play for Scotland. So I'd come but then not play. I'd prefer people just to be honest with me and say whether they really want me there or just as a back-up.
