Achievement: Balanced Path
Solution:
In order to achieve the Balanced Path achievement, you need to reach 40% personality points in two personality choices of your choice. In this guide, we'll be using Messi from Paris SG (PSG) and the two personality traits used are Maverick and Virtuoso.
The quickest way to achieve this achievement is to use Messi from Paris SG (PSG). Starting at the main menu, select the "Play Modes" section, then select "New Career". After you have selected "New Career", you'll want to choose "Use Initial Squads" and from there you'll want to select "Play As Real Player". Navigate to Ligue 1, and choose Paris SG (PSG) as your team. You'll be presented with a list of players who play for Paris SG (PSG), you'll want to choose Messi and then press "Advance". You'll be shown a "Career Settings" screen, but as far as I am aware, you do not have to alter any of these settings. So continue on by pressing "Advance" and after the loading screen you can save your career if you want to (not necessary though). Now you'll find yourself on the Player Career Mode main menu (you should see Messi standing idle on the right of your screen) and you will have £1,000,000 ($1,000,000) in your wallet. From here, you can navigate to the "Activities" section on the Player Career Mode main menu screen. Go on to the "Shopping" tab and purchase a "High-End Hybrid Matrress" and the achievement will pop.
If you want a much more simplified version of the above, read this:
Main Menu -> "Play Modes" -> "New Career" -> "Use Initial Squads" -> "Play As Real Player" -> Choose PSG -> Select Messi From The Player List" (Now You'll Be At The Player Career Mode Main Menu Screen.) "Activities" -> "Shopping" -> Buy "High-End Hybrid Mattress".
This achievement popped immediately for me after following these exact steps.
Congratulations on the achievement!!
