1. Half-assing nobody will take you seriously and you will barely get stuff done (if anything at all).
2. I personally don't want to die with regrets.
3.I don't want to live in the city anymore and live in nature.
4. I want to have enough cash to not worry about money anymore.
5. I want to impress my gods and myself.

Furthermore, you will get kicked out of your flow if you take "breaks". You have to learn to do the work despite your lazy feeling (or any feeling).

If you do the work when you are sick, depressed or angry then it will make you tougher. With that, I mean that doing the work will get easier because you have done it at your worst and realized that you can still do it and that the only thing that keeps you from succeeding are your weak excuses.

In a nutshell: Piss on your feelings and do the work anyway.

There really is no secret.
