I grew up being told
You can do whatever you want
You can have whatever you want
You can achieve anything
if you try hard enough

And as beautifully motivational and uplifting as this is

It isn't true all the time

You can't just have whatever you want
Sometimes people stand in the way
Sometimes your obstacles are too big
Sometimes its better to find something new to strive for

You can't get so set on something
because you've been told its possible
that you pull yourself apart trying to achieve it

You can't do everything
There aren't enough hours in the day

And for some it comes down to luck
