The particular thing that has created the problems of life is the dissatisfied mind of desire, which clings first of all to this life, seeking only the temporary happiness of this life, and then to these eight objects: Having comfort, not having discomfort, receiving materials (such as friends and so forth), not liking not to receive materials, having a good reputation, not having a reputation, receiving praise, not having criticism. The dissatisfied mind of desire clings to these eight objects. 

-- Lama Zopa Rinpoche
