You lose motivation because you are trying to push yourself.
You only have so much will power. And it only gets you so far.

You need a goal to pull you.
Your Money or Your Life is a better book for that.

It shows you what your life can be like when you are financially independent. And with cryptos, it can be your life for the taking. You just have to get that fire burning in you to want it.

Before that, you need to understand that it is a goal that is within your grasp.
So, just set some time aside each day for your mental training in money.
