The Funny thing about Amla was that, a Lot of people was doubting his ability in the beginning..
so moral of the story, It's not how you begin, It's where you end up! A lot of parallel can also be drawn to Bangladeshi players. Never give up hope, keep working hard at your game, Improve as much as you can...you are only helping yourself by doing that.
with that being said, Amla still has a lot more to prove, at least I hope he thinks so....
