I met with some clients who are in there mid-40s today. The wife emphatically stated that they have no savings for retirement and if they drop the asking price of their home (in a different state) they'll be left with no equity to pay off some bills. Being "mid-life" they both felt their entire life was coming to an end and they have nothing to show for it.
I was able to open their eyes to their true possibilities as it relates to how they truly position themselves for the next 20-25 years of their lives.
I have seen some people do some amazing things during their 50s and 60s. Many times it's like they've begun fresh and really created the life they truly want to live. A career is a subset of that ideal life, as well as a tremendous income to go along with it.
Just because you "feel" old doesn't mean that you have nothing to offer. Don't expect to have the rest of your life figured out at 19 years old when you're in college. You change and so does the rest of the world. Change with it, or create something new that hasn't been done.
You will truly be amazed at the possibilities that exist! You'll find that you truly can start with nothing at 50 years old and be a millionaire at 60. I've seen it happen many times.
