Welcome from Madrid Spain!
Don't be afraid of cutting. I began with June Taylor's shape ruler, cutting 2'5" strips and 5" squares. Best thing ever. Very easy. Then my first complete proyect was HST:

If you mess a bit of fabric think that you are building your stash of scraps!!!
Happy quilting and Enjoy!
