How to maek practice fun?

It's been 5 months (still amateur) since I've taken playing guitar seriously, but still not to the point of having a proper and consistent practice per day/week.

I just find it hard actually practicing ngl. The "practice songs you like" advice doesn't really work if a majority of songs I like have techniques/parts that are difficult.

So far songs I've been able to play completely (this is just to gauge my guitar playing)

- Smells like teen spirit, why bother, monkey wrench, song 2

If possible, could you recommend me to some helpful practice routines that got you into playing guitar more? Any tips help
