frustration reigns

As the subject indicates, I am quite frustrated these days. The level ofcourse varies from day to day and from one thing to another. Whether it is work life, financial, school life or personal life, there is no dearth of issues. Mind often wanders - what if the stock price was xyz, then I could do blah and not care about anything, what if I had financial independence, then I could maybe switch to full time MBA instead of part time, what if....what if .... what if....
I wouldn't call this the "grass if greener on the other side" syndrome.... rather I am struggling to find ways to make the quality of life better rather than worry endlessly about things I cannot change. Till I find the magic mantra, I guess I continue on my ek-khoj. :)
