I would go back to being 10 years old.  I would start saving all the money I could and invest it in AOL.  Buying in at $12 a share for a grand total of 1520.  Once the stock passed its record high of $90 I would have sold.    $140K roughly in profit would then have then split and invested in WalMart at $8.45 (8,284 shares bought) and Amazon at $18.00 (3,888 shares bought). 
I would have continued to go to school while my investment grew.  April 30th of 2005 I would have sold the Walmart Shares and netted $296,567.20.  I would have turned around and invested it in Google at $54 per share gaining me 5491 shares.  I would have gone and done the same things I did.  Fall in love, lose her.  Hit rock bottom and climb out of the pit and find a new hope and begin to pass it on to others.  Finally on Nov 27th 2017 ($1,056.52) and I would have netted $5,801,351.32 and my amazon investment would have grown to a value of $4,519,216.80 and expected to double within a few years.  Eventually I would sell it all.  Buy a home, spread the gospel full time for free with all of my needs taken care of by my investment.
