Trust your inner judgment. Be prepared to work for what you know is right, but avoid the insufferable tragedies of running with the infectious, and you will have invaluable tools at your disposal for the rest of your life.
You must learn how to separate a detrimental situation from which you must burn all the bridges from when you must partake in hard work that will provide you with desirable results, where you must persevere in pushing through to the end.
If you can show people how to build castles, make sure you do not neglect building and nurturing your own.
I figure, sometimes, bad things happen to us so we can achieve a higher purpose and attain greater happiness and fulfillment in life.
