Well, as you well know, it's not going to happen overnight and it certainly isn't going to be easy, but so many people completely miss out on their dreams because they didn't have anyone to support them and tell them "You can do it, just keep working".
I am just now realizing my dreams with the support of family and friends. If they hadn't been there to support me and encourage me, I would still be working in a dead end job that I hated. Of course, there are no guarantees in life and you may not be able to make a go of it. However it wouldn't be for lack of trying and it is always better to remember that you gave it your best shot rather than wonder what could have been.
