Oh, this is the economic climate to answer that one!
Every day, even as we slowly move out of the long lasting and painful recession, we are faced with more people than ever losing not only their jobs but the financial security they struggled so hard to obtain for themselves and their family. In one moment, people are wiped clean of savings, investments, careers, and security.
If their stories aren't the perfect economic lesson as to why I should trudge forth and pursue my dreams, then I don't know if there is one.
In a way, by not experiencing economic wealth as an adult, I am blessed with the perfect spring board to move forward. Since my standard of living is low, it can only get better. I do not have to worry as much about maintaining a style of living/a family since I can easily replace my current income with any number of low paying but readily available jobs.
I do dream of the day when I have my own home, my own car, have a family, and a weekend that will be entirely mine (just maybe not in that order ;-) ). But I am willing to wait until my career is has gained more stability to pursue those ends.
Ironically, these dark economic times are the perfect justification to following your dreams.
