Who's To Blame?

Some say I'm very lazy 
Others swear I'm crazy
Constantly changing
Like coastal weather 
Like Ships in a cove
I come and I go
Nothing stays the same
I live, love and move on
I tell myself I've done it all 
And yet I continue to look
For different ways to fall
I must mutate and evolve
While I wait for my wings 
to grow big and strong 
I'm no demon and, 
certainly, no angel 
you must know 
Many stories I have told
Some new, some old
Searching for a balance
between what I've given 
And what I have taken
I have no one but myself
To blame if I have to go 
through hell to find
a little bit of heaven
