I will be Stronger ( use either "more strong" or "stronger", not both together)

Since my childhood, I have had a dream to be rich twenty years later. I don't know from where that confidence (confidence = noun; confident = adjective) comes. To me, being "rich" means that I will have a big house, like a single-family detached home seen in the American films, located thirty minutes away from the city centre. When I go shopping at the supermarket or mall, I will not need to check the price of goods, just pick up the items and pay for them immediately. Do you find this dream strange? I think it is a childish dream, but I am still working towards it. As time passes......(not sure exactly what you mean here) do I need to mature/ do I need to work harder to achieve the dream? 

Just remember that money truly does not buy happiness....although it certainly can help! The North American dream comes at a cost......concentrate on your education and work hard to achieve your goals! 

I will be more stronger

In During my childhood time,I have no doubt to believed that I will would be rich in 20 years time later.I don't know where that confident confidence come came from., Being that rich would means I would have a big house (like in the American film Single-Family) villa),30 minutes away from the city  center. city;I would not be concerned with the price of goods in the shopping malls, I would just pay for them without a second thought.when I go to the supermarket or shopping malls I don't need to see the price of goods,  just take it away and pay for it straightly,  Do you find it this funny?, I think it is every childs' desire/dream a desire for a child and I am still struggling to achieve for it.   but The time however, is approaching gradually.,(am I need to speed up? I am not sure what you are trying to say in this last part.)
