When ignorance is present, from attachment as a condition, only two results can arise:
- Suffering or
- happiness that ends in suffering.
There are many ways in which we suffer.
One of them is being aversive when we don't want to be aversive.
You stated in your question that you "dreadfully struggle to tackle aversive tasks". From this, I assume, you're being aversive when you don't want to be aversive. Thus, this aversion that you have is creating a kind of suffering for you. Or lets just say that this aversion is not pleasant for you ... you want to get rid of it.
The aversion you're experiencing is because of your attachments.
To get rid of aversion, you must destroy attachments.
How?
Totally calm your mind. Empty your mind.
From total emptiness, make an effort to arise any thought you wish.
Observe how the thought arises.
Once the thought arises, observe it. Look at it. Note it.
Then, in the same way you made your mind totally calm and empty, repeat it and observe how the thought ceases.
Do the above many many times. Don't do it just with thoughts. Try it with anything you can feel with the mind sense.
Do it with sounds. Listen to a sound in your mind. Then, in the same way you made your mind totally calm and empty, repeat it and observe how the sound ceases.
Do it with any mental formation, like a visual or sensation of smell or sensation of taste or an idea or a concept ... anything that you create in your mind. Then, in the same way you made your mind totally calm and empty, repeat it and observe how the mental formation ceases.
Do it when you're hungry and you crave to eat something delicious. Then, in the same way you made your mind totally calm and empty, repeat it and observe how the craving for food ceases.
Do it with your emotions, like fear or anger or sadness or nervousness. Then, in the same way you made your mind totally calm and empty, repeat it and observe how the emotions cease.
Do it when you're bored to death. Then, in the same way you made your mind totally calm and empty, repeat it and observe how the boredom ceases.
Then, do it with aversion. Then, in the same way you made your mind totally calm and empty, repeat it and observe how aversion ceases.
If you can do the above successfully, as described, you'll see why aversion arises and why it ceases. You'll see it. You'll see it. Seeing it, you'll know. You'll know.
Knowing why it ceases, you'll make it cease whenever you wish. And no, you won't need to go in meditation in order to make it cease. You'll just do it. Like moving a finger.
