5 secrets to building your business

I've been reading this free ebook on building your business and I really like one of the main points - setting up specific time for money making activities in addition to separate time for running your business. I've been caught in that trap of spending time on running the business and not dedicating time to money making activities. You can see some additional information on their website http://www.marketplacestrategies.com.
Much of what I read is too basic, not applicable, not realistic, not helpful, etc - but this piece of advice is smart.
