Analysis of I'm directing a movie

I had a very wise life coach
My grandpa with his gentle touch
Telling me different stories
About what actually means life glory
"My grandchild", he said
You know when you're really fed?
I looked at him carefully
As at a wizard on TV.
It's not about money
It's about not being lonely
You know how to get it?
By being able to sit
In front of your reflection in the mirror
And not seeing in it the error
You're allowed to be weak
But not to be creek
In which someone will die
And you won't even cry
Don't ever do that to yourself
'Coz I promise, you will regret
If you can't look bravely at yourself
How do you imagine taking someone's help
'Coz anybody can make it happen
If they crumple a heart as a napkin
So with my mindset I colour the view
Making my grandpa's dream come true
