I always have a book that I write during competition. I need it with me, just to read back and reflect and look forward. If I'm feeling anxious, it helps me.
In 2012, I was over the moon to be there, especially as it was our home Olympics. It was a once-in-a-lifetime experience, and I just wanted to take everything in.
I've got so many big gains to make in the javelin and the shot put. I know I'm not going to be winning the field in those events, but I need to do myself justice.
When you see all the medals won by Team GB, you can just see how much it means to each and every athlete, so it just feel like it's a little bit of a missed opportunity - but I'm only 23. I have just got to get on now and keep going.
I've always known that Rio and Tokyo are my two Olympics. Now that Rio hasn't gone to plan, Tokyo has to work, and I'm more motivated than ever.
