If you could rewind time back 8 years, what would you do diff?

[Craig Moore]

BP,

This question arises from a goal I've set for myself to become a millionaire within 8 years (my 30th birthday) and have a monthly rental income of $10K+ (this is the minimum) a month.

So, knowing what you know now, if you could get those 8 years back, would this be possible for you? Is this a reasonable goal for me (I'm still going to try even if it isn't)? Would you get it sooner than 8 years? What was your steepest learning curve?

Thanks in advance for your answers/perspective.
