...I was 14yo when I started surfing - a mate of mine found a grotty old 7'2" 70's single fin in bulk rubbish (council collection) and sold it to me for $2. I don't recall having any trouble getting up - but can certainly remember the feeling of trimming my first 1ft shorebreak - I was hooked!! Apart from injury, I've been going as often as I can for the last 29 years.
yup I first stood up around age 11 (year 6 at school).
I had a lid before that
.
One School holidays we stayed at a family friends farm out at Permona (Noosa Hinterland) . I did a weeks work on the farm , in return I got an old 1980's thruster with channels.
The following week I spent all day every day in the water at 1st point Noosa.
I clearly remember some of my first few waves as a grom just doing this gumby bouncy trim thing.
I was soo stoked , happy and beaming with life.
I have been addicted to surfing ever since.
Life is great 
me brother pushed me in white water, already standing, when i was about 4 and 6.
I clearly remember the first time I cried the whole paddle out but was pumped when i would hit the shore.
me first tube that I made where i could see the lip hit the water in front of me; I was 14 or so except I remember the grin i had afterwards more vividly than the wave.
What a grin it was.
