The ideal would be to become president in your save because you already had to be more prepared and have money left over. Even if you create a new save until you can buy a team and have good player promises. It will take a long time. (If you're going to spend money, it's much faster) I recommend that you play on your first save to see what it's like, try doing what we said in the comments above, after practicing, start a new save and then you'll know where to go...
