I am fully aware that cricket is like a second religion in Pakistan.
In my heart, international cricket is the way forward. That's where you want to play; that's where the pressure really lies. That's where you make your name.
We all grow up dreaming of playing international cricket.
I was brought up to always see the glass half full instead of half empty and played my cricket that way.
I have been massively proud to have played for and, indeed, captain my country on the cricket field.
I'm a bit undercooked when it comes to keeping in Test cricket, but I've had a lot of experience in T20 and ODIs for my country, and my keeping has improved a lot.
I will always be grateful to the coaches and staff of Cricket South Africa for their support through all these years.
I can't keep playing 10-11 months a year and keep being sharp after 15 years of international cricket.
Money wasn't the motivating factor in calling time on my international career and focusing on T20 cricket. If I was here to make as much money as I can, I would be playing 10 to 12 tournaments a year.
Test cricket is the ultimate challenge.
