The problem is that just like with any self-help technique, the pursuit of tricks to live your life by can easily replace the living of your life. The time you spend getting ready to live is time you spend not living. The time you spend learning to speed-read is time you're not spending just reading.
These things are supposed to give you more life to live, not consume your life. If the pursuit of "life hacks" is a hobby for you, then I suggest you're doing it wrong.
I've never heard of life hacks consuming someones life. If there's a way to wake up earlier, you just saved time. If there's a good way to organize, you just saved time. If you just learned a way to read faster, you just saved time. All of these life hacks take maybe a minute to learn, 10 to setup/master. If for whatever reason a life hack doesn't work and you wasted 10 minutes... Well, you're on the internet. Wasting 10 minutes is something you can afford.
Here's another life hack. If you trust yourself, use cash more than a card. I usually do this when I'm going somewhere and I have a limited budget. The physical appear of money really helps you consider whether or not that you are buying is worth it.
