I have learned that in life nothing is more important than family. When someone in your family seems not to understand that, be patient, they will eventually come back into the fold and protection of the family.
Also while it is good to be positive in everything you do, be aware that there are too many people in life that manage to get ahead by causing problems for others. Identify these people as soon as possible and beware of people that tell half truths or lie by not telling what they know, even when asked -unless it will benefit themselves.
There is nothing better than working for yourself. It gives you more time to be closer to your family and keeps you farther away from the type of people mentioned in the paragraph just above.
