People often leave the thing they dislike (or simply like least) until last - then seem surprised when it seems to work.
Where does this surprise come from?
The thing you put off is usually the reason you tried the others first - They weren't as painful to attempt compared to admitting that your likes and dislikes could be wrong and that you need to start with a fresh new approach that is more likely to work. So everyone tends to fixate on the things that they could do that could go wrong or that they may do poorly in such an attempt. This results in them doing the things that would usually make them hesitate, with more mindfulness and discipline than all their other attempts. Close enough isn't good enough for the things you try to avoid. You only want to do this once! When you attempt what you think is impossible you tend to be more diligent and want to take notes so you can throw it back in the face of all those that suggested it to you. Throw it in your own face for even contemplating doing such an unlikely thing ...
The discipline, the mindfulness and the methodical diligence you apply to your task are what makes it work - Not the fact you hate it.
Having the painful things work opens your eyes to what you have been missing - the ability to access to a more honest and authentic place in the world. Shying away from the truth you see in those moments and convincing yourself that the world is against you will get you know where.
Using the memories that come from times of learning that stick in your mind and skills gained from those experiences will help to startle yourself awake and to open your eyes wide and see the real complexities of the world as it is. Such a view is priceless ...
