obeying one's parents

Q: I always faced the issue of how to handle the negativity from parents. I always tend to believe that as a child, good qualities were always acquired from other relatives or good personalities Allah gave in my life but not from my parents. I'm in struggle between the fact that they are my Wali but have had hard time putting up with their character and practices! I'm answerable to Allah if I don't have a right attitude towards parents. But I am not able to put up with their negativity. What to do?
