Emotional hurt, you gotta let that go. Walk away and let it be. So many highs and lows, but if you keep being down, you'll never get up.

You can't let the highs get too high and you can't let the lows get too low.

I knocked a lot of guys out from the seventh round on - so if I gave up, I would never have achieved what I did. There was no giving up. It's weak to give up. The easiest thing in the world is to quit.

I think the highest and lowest points are the important ones. Anything else is just...in between.

To get 50 caps you have to go through highs and lows - and I certainly had a few - it has never been rosy but to be still here, as well as enjoying good times at Celtic is very pleasing.

Everything I know now . . . the pitfalls, the highs and lows, everything . . . it taught me and made stronger.
