Mainly my indecisiveness and money. I couldn't make up mind for the longest time as to what I was going to build next and when I finally did something came along and it totally changed my direction of planning completely. I made a few purchases, but now I am second guessing myself if I did the right thing. I hate to half ass anything when it come to my car and I find myslef making more and more compromises on this buildup. I like to research EVERYTHING I do to my car before I do it, but there are so many options with the route I'm starting to take that I just don't know which is the right direction for me. I HAVE to have the car done by the time the baby is here, so I need to really start making some decisions soon, but I just don't want to be second guessing myself down the road as once this build up is over, the car is DONE in terms of performance. I don't want to ellabortate much more on it at this point in case I do in fact sell what I have already purchased and go in another route.
