You may be trying to focus on too many things at once. If a state-of-the-art computer can only have so many programs running before it crashes, why shouldn't the same be true for you? Figure out what you want to worry about and what should be put to rest for now. Otherwise, you'll overextend yourself and then you'll have to waste time brushing yourself off and recovering from the stress of it all. That would be no fun at all. It's far better to take some proactive measures.
