The best way to keep things fresh is trying to learn a new skill every year.
I only made 4 static-line jumps my first year.
Over that winter I earned a private pilot license.
The next summer I flew a bit and only made two jumps.
The third summer I made 60 jumps and earned my A license.
The fourth summer, I did about 50 fun jumps.
The fifth year, I passed the army static-line course and tried out for the Canadian Army parachute display team.
The sixth year, I earned a static-line jump-master rating.
The seventh year, I did another 50 fun jumps, plus a stack of exhibition jumps.
The eighth year, I earned a rigger rating and started flying jumpers.
The ninth year, I flew more jumpers and learned how to drop IAD students (1985).
The tenth year, I earned an Instructor B rating and tandem instructor rating and did a couple of BASE jumps.
I did not jump much while at university, but worked full-time in the skydiving industry for 18 years afterwards. Every year I tried to add a new rating or renew an old rating: Master Rigger, PFF instructor, Cypres installation rating, PIA Symposia, lecturing at PIA Symposia, wing-suit, Rigger Instructor, Rigger Examiner, Tandem Examiner Rating, etc.
Eventually, I had to take a year off for knee surgery and cut back to only doing tandems on weekends. I finally quit jumping after the local CSPA DZ shut down and I disagreed with a non-CSPA DZO about seat-belts.
If you try to learn something new every year, you will never get bored skydiving.
