Best way to study economics?

Well I was absolutely and utterly trash at economics, i never really grasped the concepts but i eventually thought of creating my own nation with a small number of people laying out the financial framework of the nation, creation one central bank and 2 commercial bank i started with national income then circular flow of income, money and banking etc this way I grasped the topics clearly and understood the cause and effect relationship of everything. Oy after doing so i realised that this way of learning economics when you create a fictional national with realistic numbers and values is referred to as economic simulation.

I think it a really interesting way to look at economics if anyone else did it this way I wanna know from them.
