Here's another suggestion: Find a quilt design that does not require seam matching, like bricks, or strippy quilts! As a beginner, your best bet is to attempt something that you can be successful with.
Also: Your blocks are not that far off. Some mis-matching can be compensated with by pinning the seams together and easing in the excess on one block. Or, you can find the wonky seam and re-sew it to even up that block.
When I began quilting, I was an experienced sewer of clothing and household items, but it took me awhile to really absorb the special rules of quilting, especially the emphasis on keeping those seams straight and even and the same size, over and over again. It comes, but it takes paying attention and doing it over and over again.
Best of luck, and keep on asking questions!
