I am extremly undisciplined. I've been procrastinating my whole 21 years of age and I'm fucked if I do not change my ways.

I just wanted to know how some of you guys who were in a similar position did it.

How did you manage to change yourself?

What books did you read?

What videos did you see?

What posts / articles / anything did you read?

What mindset did you have?

What concrete steps you took?

Myself am trying Cold Showers and meditation but sometimes it feels like I'm using them to avoid the work and feel good about myself. I need your help.
