The captain of your own destiny

I'm the captain of my own destiny,
it's challenging me.
Being the best you can isn't easy,
trying to see the good things in life,
while falling,walking, climbing and than dive,
I don't know what to expect or which way,
but I know I have to stay.
People on this trip will come and leave,
helping or disturbing the goals I want to achieve.
I'm trying to be my own best friend on my own destiny, and trying to be who I want to be.
