Just like working out, occult training can feel like a chore sometimes. After a certain while it does start to feel like doing the same thing over and over.
How do you get over the issue? Problem isn't the lack of discipline in the question mind you, or the lack of progress. I am more talking about how things get stale after a while.
Good question but difficult to answer without a deeper knowledge of the situation.
It is worth remembering that the mind is not the same thing as Essence. The mind has largely been given to us by a society which wants it to run the programs useful to that society. Those programs run very,
very deep. The mind also has an inbuilt firewall that will "protect" against any programs which might put the mind to uses other than those socially approved. This ranges from "magic isn't real" to "this is boring, give me something more exciting". This is why any genuine spiritual Work, where we train the mind, is so difficult. Your feelings of boredom may well be part of this; the mind trying to sabotage Work that it knows, subconsciously, is yielding fruit, even if it's not visible yet.
That being said, if a practice has been going on for years and has become completely arid and nothing is changing after persisting with it, I would then say it's time to throw a curveball and work through one curriculum of a
completely different system for a few months. Then return to your original practices. If they immediately bore you again, it might be that you've outgrown that system, that there's nothing left there that resonates with you. If, on the other hand, you feel energised by them you'll find that your practice is better than before and you'll probably see the practices in a new light.
Another question I have in mind, do you guys relax in order to meditate, or meditate to relax?
Relax to meditate. Relaxation is a good thing anyway but it also, ironically, puts us in a place where we can make relaxation work for us. However, it's also important to relax without meditation. We should spend time "doing nothing".
