WHO AM I?

When I was a kid I used to worry myself a lot about who I will be when I grow up
Many years later "Who am I?" is the question that's tearing me up

Am I that 12 year old genius boy that every teacher and parent banked on?
Or better still, the teenager who had his way through all kinds of vexation?

Except this one time he was caught in the act and had to gnaw raw green maize

At times I think of myself as that adrenalin filled juvenile on stage to amaze

But, I realize that it is all dead and gone so I turn to my quiet side of life, is that it?
Five years later a profuse sequel stems from him when all seemed fatalistic
Who am I?

An apprentice with a great ambition just as they had predicted, I wonder if I'm him
Always taking chances when interested and has his way through his aim

Never been disappointed, well, hardly been disappointed
 If I am him I will be really disenchanted

Very bright light shinning at the end of the tunnel with the hope that it is not a train
I think I know who I am, I'm the future trail...
