Valuetainment in youtube combines all the books you can ever find. What i learned so far from it, others and all the books - don't listen to anybody. Things like: discipline, know your priorities, read books, have a vision in life, change your mindset , create a to-do list, work out, take care for your health, woke up early, create value to others - won't change a sh*t.
One I can agree on - hard work beats talent.
