The Time May Be Different, Just Not This Time

I cannot be what you want me to be
Back then I was a child
Now I've seen and tried different things
I've turned out a bit mild
I wish I could remind you, of how I once was
But those times have passed through
Changing the way you may perceive me may be difficult
But I'll always continue in my own way
I will try to persuade you, every single day
