🚀 Как достигать своих целей с Live Driving (c)
Например: "Выспаться", "Выучить английский", "Запустить свой проект", "Быть счастливым" - все эти цели вполне осуществимы, я бы сказал, что они жизненно важны.
Тем не менее, руки не доходят до собственных проектов, а счастье кажется где-то в далеком "светлом" будущем, которое может и не наступить.
Оглядись вокруг - мы уже в нужном месте, в нужное время, прямо здесь и сейчас. Все уже случилось!
😎 Некоторое время назад я создал свою точку опоры для достижения целей, которую назвал Live Driving - посредник между человеком и окружающим миром на пути к достижению целей.
Мы встречались 29 октября в Алматы - было здорово, как и всегда на наших встречах. Также есть мысль о встрече в Астане.
🔻 Кто хочет получить позитив, добро пожаловать - заполните форму участия в Live Driving.
