One lesson I took from my mother is, always smile even at your saddest moment... It may not be the ideal situation, but being sad about it changes nothing...I will always smile as I walk my every mile after all the world will only but watch while I cry alone, it'd rather watch me smile... The other lesson is go as low as life demands, there's so much for you to learn in the valleys of struggle, most of which will help you successfully hike the steep mountains of success.
