I don't think I've done home renovations myself. I don't trust myself in doing a good job of it, and I find it is better to trust those who know what they're doing. I have done some maintenance, like fixing a hand rail, working on leaks, and other smaller works. There is some sense of accomplishment when you fixed a problem. I hope you are able to make the kitchen of your dreams, and be able to build it by yourself.
Yeah, it can seem a little daunting.
I've done a lot of it, renovated many houses, but only once have I renovated the house I live in personally - I still have that house too, the original renovation I did still looks good. It was a lot of work though.
You're right about that sense of accomplishment, for me it's more about that than reducing the cost by doing it myself although both are a good win.
