Start with a ridiculously short time frame.
Extreme example:
Every day at 6 in the morning you read for 10 seconds.
Then you clean your room for 10 seconds.
You work out for 10 seconds.
Do that one week. It will feel like you did nothing but it will also
feel like it was no problem because the 10 seconds were over fast
before you could even start.
Next week you do it with 30 seconds. It will maybe still feel ridiculous
because you can´t read much, clean much or workout in 30 seconds but it
will also be over fast.
Increase the time every week. Use the timer on your phone
I did that with jogging when I was 31 and I never did any sport until then and was super lazy. I started
with one minute and after one year I was running a half marathon and I was running 30 minutes in the
morning 3 times a week before I started my work day.
This taught me discipline and it started to feel satisfying and I trained my brain that I can achieve
things and that´s how I learned all kind of things and that´s also why I have now a super clean house.
You have to imagine that I was a very depressed and chaotic person and that I did whatever I wanted
my whole life, bad at school, probelms with authority + I was drinking and drugging. I had no mentor or
teacher, I figured this out by reading books and training myself
