We can all relate MissKnit!
It takes experience before you can look at a project and know whether or not it will be fun or boring! Scarves do take a lot of knitting!
Are you doing garter stitch? Knitting every row? If you're totally bored, you can switch to doing all the purl stitch and practice your purling. (Purling every row also gives garter stitch.) To make the switch invisible, break the yarn (weave in the end later), and transfer stitches to the other needle, and start again on the other side of the scarf, doing all purl stitches. You'll still get garter stitch, and you'll get good practice on your purling!!
If you do this, just keep an eye on your gauge, you may need to change needle sizes to keep your scarf from getting noticably wider or narrower (since you may purl at a different tension than you knit).
