questions, and am i wrong?

kay, i dont know where to start,

People dont seem to understand why i put so much money into cars. but tell me if this is wrong. i put all my money into my cars and girlfriend because i dont want to turn out like 95% of teenagers that spend all their money on booze, or short term happiness, i want to be the teenager with the nice trucks, cars. and go somewhere in my life by the time im 25. but is this wrong to think like that?

and i have a couple questions, will it be very hard to weld my willys together, and put the 9" rear, front end components, and engine tranny in it?

and are belltech springs any good? my dad got me some for my 1991 f150 and i would like to know ife there reputable..
