work and no play makes me a very dull girl

Well now I feel I am at a point in life where I need to embark on career enlightenment...decide what I'm doing with my future and my love life. Decisions I like to typically procrastinate on...but when certain events occur in life, it makes you take a look and think about things. My coworker was forced to retire...a couple of months before he actually is of retirement age. This after 22 years of dedicated service to our company. What does that mean? He probably feels slighted and dejected because the company he stood by for so long has let him down. It's all about the bottom line and not sure if I was kidding myself before. Is it ageism - cheaper employment for the next hire? Whatever the case may be, why be loyal to a company who will one day turn around and stab you in the back. I want job security but who knows what will happen around the corner? And when I get old? What then? Replaced by newer, younger, cheaper models? So I thought, I need to start my own company - I can lose money or whatever, but can't really fire myself. The problem is - what kind of company? I guess I'll have to brainstorm and come up with ideas.
