All of these ideas - what to do?

Have you ever had too many ideas? I have spent a long time trying to figure out what to do with myself after my sudden departure from my last job. Now I am closer to figuring out what I want to be doing, but I have too many ideas! If I start them all then I am worried that I will not be doing any of them justice. Drawing the line between too much and too little is the key. But will I be able to see the line once I draw it? I am committed to this blog (this was the first in the line of ideas) and I am going to keep this up - even if I never share it with anyone! And I have been spending days working on one of my other ideas - as soon as I have it set up I will unveil it (to myself) here first! Do I stop and focus on these two ideas for now, or do I let myself go with the third idea I want to start? I will sleep on it tonight and decide tomorrow. Having spent the last few years with a total fear of commitment - can I really commit myself to three different ideas at once?
