I'll offer my $.02 for extended dynasties. All help, in no particular order:
#1) I find, in the past, my only way to commit to multiple seasons is with a team I am passionate about, or the end goal of
becoming that team. I could play seasons on seasons with Boise State, they're my team!! I also find it perfectly fun to work my way up to earning the job at Boise State, which I think took 4 years last time I ran with them.
#2) To combat RIDICULOUS success rates, you
NEED NEED NEED house rules. Not just in terms of gameplay, but also in recruiting. Read through the "Dynasty House Rules Ideas" thread below:

It's long, but it will do wonders in keeping the game difficult. Change your sliders, curb high end recruiting, try to recruits "true to the team" if you will. a 2* program getting 4-5* recruits is not only unrealistic, it leads to failed dynasties because its too easy. Force yourself to use your OC's playbook, not your own. Limit how many times you call "money plays"...force yourself to open up that playbook! (both offensive and defensive). It creates a much more difficult time, which is more realistic.
Sliders do amazing things to make this game harder, btw.
House rules and sliders are HUGE. I'm entering 2020 with Sonoma State and have not won a title yet (lost it last season 38-31 in my BCS championship debut). I've never had it take this long, it feels so much more organic, and way more fun.
#3) Document your dynasty, in some way. Keep track of each season: opponents, scores, key players from each game (on both sides), your stats, etc.
This gives you a way to look back and remember past seasons. It can create more storylines to keep you interested. IE "ok were playing Boise State, last year we lost 31-10 when Kellen Moore shedded us...can we keep him in check this year? (or maybe he graduated, do you have a chance now that he is gone?)" just stuff like that. For me, I start to waver in dynasties when I no longer remember how past seasons played out. It helped me a lot to start a dynasty thread on OS. You don't need to make a novel or thread, but even just a word document/spreadsheet where you keep info will breathe life into years 4, 5, 6 and so on when you lose interest. I'm in 2020 for my teambuilder Sonoma State...furthest I've ever been. A big part is because I can tap into my thread and see how games went, how last meetings with teams went, who won the bowl games, etc etc etc.
#4) Don't be afraid to change directions in your dynasty. Maybe you're 3 years in, and doing well with Idaho...but you get offered a new HC spot at struggling bottom feeder Washington State (or another power 5 program that has struggled a lot)? Take the job! Be a real coach, and move up the ranks. That can refresh things for you.
#5) Make stuff up! Doing a bit too well? Ok, your QB just got kicked off the team for a drinking escapade. Your star running back hurt himself in practice...etc. Find ways to bring realism to it, get guys off the field. Hold guys out for "injuries" since NCAA has way too few of them. If it feels real, you will like it more.
Hope these help!
