I speak to people who have coached me down the years who tell me to look at how far I've come and to just keep going, there will be light at the end of the tunnel.
You have to create a habit of finding the right positions and knowing where the ball's going to bounce to.
I would be kicking a ball about with my friends and they'd ask why I was wearing the Celtic kit.
I enjoyed it at Celtic and had some great moments and obviously some not so great moments.

I don't like to put much pressure on myself but yeah that is my sort of football: get the ball, run with it, use my pace, create opportunities, cross.
I love playing for Scotland; it's my country, it's where I was born, and every time I wear the badge it's a dream come true - goosebumps.
