My current plan right now is kind of a way to slowly trickle my unused liquid assets into lesser and lesser forms of liquid assets:
I save 10% (at most, or generally what is feasible because of finances) of each paycheck for investments.
Saved investment money is put into a savings account until a certain balance is reached. The account will be upgraded at my discretion if I feel it will be worthwhile.
Once savings account balance is reached, a portion of the savings account balance will be transferred to a money market account. Future saved income, then, will be split in half, each half deposited to the savings account and the money market account.
Once a certain balance is reached by the money market account, a portion of the money market account balance will be utilised for mutual funds (most likely), stocks, and the associated fees. A portion of the savings account will also be used, at this time, to purchase certificates of deposit.
I've been taught to be frugal with money (even when, delicious irony, the people who taught me were the ones who were terrible with money and didn't want to admit it). As such, even though this is a long plan in the making, it has always been a plan for me to have some form of savings that I can rely on for emergencies (the savings account) and when I get older.
So, ATG, my plans are a bit grand, but I think it's doable. What do your investment plans look like, if they exist? What do you think other people should consider in any financial plan? If you don't plan, why don't you? If you do, why do you?
