Do whatever seems important to you but be clear on your motivation.If it's meeting your needs, say so....there's nothing wrong with that. People who get off on the kudos of taking up a cause or helping other people are still not wrong....as long as they know themselves well enough to know that's what they are doing.
In a career of supporting and working with disadvantaged people, the ones who 'want to help' without awareness of themselves or their limitations are the people I most dread coming into contact with.Altruism makes me nervous.
