The reason people have issues sticking to programs are simple.
1. The program is over ambitious
2. The program is too long
3. The program is tedious.
I'd add to these good ones ^
4. You don't know why you are doing the program in the first place.
5. You don't know if the program will deliver the results you actually want.
85% is just showing up.
IT's 85% DIET ANYWAY.
In the realm of general/personal fitness I question the need to be on a program all the time if at all. If you record your activities and apply some form of load/volume periodizing you'll get results.
If you are looking for specific results for competitive advantage is a different story, but then it might pay to have a program designed for you specifically if you can't find an off-the-shelf one that's a good fit, that you feel will take you to a destination and holds your interest.
You can go from program to program and you aren't going to perpetually improve. You are only saving yourself the trouble of doing some reading up, some self experimentation (how do you think the authors of all these programs came up with them in the first place?) and making a rough map of how you will measure your attempted progress.
Learn good form, show up, do the work, eat for the plan. If it is killing your enthusiasm, change it.
