doubts

So here I am, 8 months after I purposefully started on the search for the PhD program and 8 months from hearing where I will be in 12 months. The last 8 months has been a very exciting period for me, with many ups and downs. On a few occasions, I questioned whether this is really what I want. Do I really want to give up the comfort that my family is having and be a hand-to-mouth student for the next 4 to 5 years? Do I really want to put my wife and child thru this? Do I really want to give up the business that I have been establishing for the last 8 years?
