Dhammapada: Yourself

"You are the source off all purity and impurity.
No one purifies another.
Never neglect your work for another's, however great his need."
Don't blame others for your short-comings and don't expect them to fix you. They might give you advice, try to help you, but you have to act on it. You have to be the one to make the change.
By the same token, you can't 'fix' someone else. You can offer aid, but they need to save themselves.
If you always put yourself last, you will never improve, you will gradually wear away. Then, how can you help? Look to yourself first, then you will ensure that you will be present and able to help others.
