What would Usain do? Would he tense up and fret? Would he sit in front of the X-Box all day? Would he train so much that he exhausted himself? Would he kick up a stink when his trainer (mum & dad) suggested he do a bit of practice?
Probably not. He'd 'work, rest and play'; he'd feel confident in himself; he'd work on the last minute things he could fix; he'd be really concentrated. Most of all... he'd be up for the challenge.
Do an Usain this Easter! Hover over the picture to see Usain's acceleration. This is a metaphor by the way!
