If you just invest in Blue Chips you might feel really blue but if you just invest in hot exciting stocks that next cliff might be too high to climb. It’s a balancing act because you never know when a new expense will come your way (car breakdown, house emergency repair) so you need to keep some monies in a nest egg. That nest egg can’t be so protective that you watch all the excitement crack before your eyes. The key is to first insure you can pay for your basic necessities (food, water, shelter etc) for the next several months should something occur with your dream project. If you can get through this cycle then make sure you would be happy if you lost the other aspects of your life (cable TV, restaurants, Going to the movies, new clothes etc) if your investment panned. Once you balanced these costs you can determine how much to invest in that movie, new company or even Atlantic City. Have fun but with your head involved not just your heart.
