Want

For some reason, lately I've been seeing wanting as weakness. To want something too much puts excessive expectation into the matter. Hope for a job, a relationship, or any other result can often lead to disappointment. But harboring too much non-attachment is also no way to live. A balance should be sought and letting go should be practiced. However establishing and adjusting that balanced tightrope walk can be truly difficult. When do you know when to let go or when to hold on a little more? When does wanting something become harmful instead of uplifting?
