Hey brother I totally hear you on this. I am also a giant geek and have collected comics and action figures for most of my life. There are points where I look at the list of what I want to do and look at the amount of time I have in a day and just go Ahhhhhhhh. It can get crazy, but I always keep pushing trying to fit it all in. I learned a long time ago I just have to interweave everything or I will never make it. If you do start with the knife making let me know cause that does sound extremely cool and interesting.
