April Results

I guess it's been a while since I posted, so I will post some results from last month. April has been my most successful month ever as a poker player. I got 2nd place in FTP's Sunday Brawl and I won a big daily double tournament as well. This netted me about $47,300. It was a big boost to my confidence and big pick me up to my bankroll which was hurting from playing NL(4) at the beginning of the month.
Right after I got 2nd in the Brawl, my poker playing probably got cut by three quarters. I have heard ghost stories of friends going up in limits on cash games and trying to beat tough games just because they had a big tournament score. I was determined not to have this happen. Leaking this big tournament score to the cash game players would be retarded because my month in Vegas over the summer is more important than stroking my ego by playing NL(10). With that said, my main purpose is to have $30,000 of my big score turned into liquid cash, which is much more difficult and time consuming than I anticipated it to be. 20gs going to expenses and my bankroll for Vegas and 10gs going into a CD for next year's tuition (tuition alone for my school is about $40,000 a year).
So April came about new beginnings for my poker adventure and I now have a new problem:
How to build on $40,000 instead of locking it up or spending it all?
