Like wot Andy Says
It is really hard sometimes if you are working alone and have nobody to push you along. Every time you hit a problem it's hard to keep the motivation going. The pleasure in finding and implementing the solution always makes up for it in the end. I have been there with my side panels, I just could not get the confidence together to get on and do the job. Lots of help and advice from several forum members made all the difference, I am now well on the way to getting them done.
All the best with the build, you can do it.
