Say you could go back in time when you were like 12 or so. (Im not 12 lol) And you could do something differently. What would it be? And Why? We're talking like Computer and Your Job choice. Not like "I wished I woulda married a rich girl"
Nothing will be changed everything will be same , as same you are the same person so nothing will be change.. But if you were someone else .. everything will be change .. we don't have time machine .. back to reality. even if we have time machine we can't change the past or the future. But if you willing to change you could start with your self and change for better that you worth of course.
I would have started my website earlier. I started when I was 22 and I'm 24 now. Even though that isn't old it would have been handy to start about 10 years earlier!
