Talent is nothing without Hard Work. You may have the strength. You have the skills. But if you do not put in your effort into training, you will not achieve anything.

Usain Bolt is one example. Possibly the fastest man on earth. But if he does not train hard, he can't keep that title and will be beaten one day by someone else (which has already happened).
