There is no Can't unless you choose it

Peter, Peter, pumpkin-eater,
Had a wife and couldn't keep her;
He put her in a pumpkin shell,
And there he kept her very well.

I have read that this was in reference of a wife that was not faithful to her husband.

But could there be another hidden meaning:
Peter had a wife that he did not want to assert herself.

Do we know someone that will not assert their own thoughts to the people that are closest to them? For so many years, there are so many people that give in to someone because of so many reasons: they don't want to make waves, they feel that they are doing the right thing, they have lived a life of not being able to assert themselves due to their home life, and this list goes on. 

Now is the time for all to embrace their inner beliefs and not just sit back and let someone run over them. I am not saying that we need to just run over the feelings of others, but we do need to stop believing that we can't do it, just because someone has told us that we can't. There is no can't unless you allow it.
