Never expect too much from people.

Never get too attached to anybody. Attachment leads to overexpectations and expectations sometimes lead to disappointments. Yes, we may need a little help once in a while, but learn to not depend too much on people. They tend to let you down and these disappointments may cause a major set back in your affairs if you ain't braced up for the possiblity of being disappointed. Disappointments, when not properly managed affects our well-being thus leading to depression and other negativity. If you don't expect much from people, you won't be disappointed if they fail you and this will make it easier to move on and figure out your next move.
