Do you have to make a choice between being content and being ambitious?

There has to be a balance between ambition and contentment. It is good to achieve and ambition can be just the pursuit of achievement. It is good to have ease of mind. Contentment is just ease of mind. These two words do not necessarily exclude each other. However, they can exclude each other if we are being selfish about our ambition. There is no contentment with selfish ambition. They can also exclude each other if we are satisfied with failure. There is nothing ambitious about being content with failure.
