Forty-plus years of resentment and hatred toward my father, and it all disappeared in what my wife described as "a God moment." I always thought my dad would die and I would feel the resentment and hatred until the day I died. But that all changed in a few seconds when I told my dad I loved him -- and actually meant it.
I can tell you from personal experience that chasing your dreams is hard work. There are many ups and downs. There are many days when you want to quit. The best thing you can do is to take it one day at a time. Instead of focusing on the big changes you want to make, focus on waking up and doing what you have to do that day. You'll look up after a while and realize you're there.
