It is common for someone who is starting out wanting to do everything that there is to do. But often times, along the way, he will realise that it is not probably the best way to go at it. Yes, you might know how to do all the things that needs to be done but the limited resources of time and energy needs to be properly managed. Focus on what you do best and outsource the rest of the work to others. Besides getting your sanity back, you might also notice that more and better quality work was accomplished by doing so.
