You're not a lazy person, you're just procrastinating.
And procrastination can be cured...
The night before...
The night before a big deadline, we finally get the work done. Why?
Because the pain and pleasure we think about changes.
But, that change was out of our control which leads to stress, worry and poor quality work.
How to get a lasting change
You might think "I've changed before but went back to procrastinating"
That is because you only made a short-term change to your pain/pleasure balance (most often externally like the last example).
So, to create a lasting change, we change what pain and pleasure you automatically link to your work.
Then, working will be as effortless as procrastinating use to be.
