Tip #1) Do Business Generation FIRST - This means before you do ANY of your work, do business generation. This is helpful because doing it this way means that it will be a priority for you... and doing good work for your clients will keep you motivated to get their work done on time as well. Remember, you need a lot of new business when you're just starting out, so focus on doing biz gen FIRST.
Tip #2) Do Biz Gen DAILY - Form the habit of doing business generation EVERY DAY for at least a month before you slow down... you'll be surprised at how much you can get done if you do it daily.
So, do business generation, and do it daily... that's the key to going freelance and getting all the business you need.
Hope it helps some of the newer guys.
