I don't like the notion of "hacking my brain".

First, it can create long term unwanted needs, such as requiring you to treat yourself for every little achievement. This could lead to a lot of things - weight gain, guilt, or all kinds of addictions (coffee, games..)

Second, I think that improvement is achieved by slow and consistent practice. "Hacks" are... well, hacks. They aren't supposed to be used over and over again.
