We receive millions of information every day - gigabytes of data go through our brain. What is tested? What is important? What shows you right direction? Where is business? The answer is MAN. Do not look for mentors, do not waste your time and energy. We did it and we want to share this with you. MAN exists thank to our authors prof. Andrzej Blikle, Grant Cardone, Brad Lea, Anna Jakubowski, Andrzej Śmiech, Jacek Walkiewicz, dr Mateusz Grzesiak, Magdalena Boratyńska and others - thanks to them we can be better. Learn, grow - be great.
