This trophy is likely the most time-consuming one of this platinum. You will need to achieve Tier 3 Personality with one of the traits at 75% in the Career mode as a player. The 75,000 personality points (and often even 90,000 due to a bug that happens randomly) that are needed for Tier 3 personality are a huge amount of points and will take between 7 to 10 seasons.

You earn those points by:

• Making decisions in the Actions tab.
• Buying items in the Actions tab (to earn money for them you need to make investments).
• Training.
• Playing matches.

The main issue here is that playing matches often gives you personality points for all three types (Maverick, Heartbeat, and Virtuoso). Through certain actions on the pitch, you can control the point distribution to some extent, but in general, it is hard to maintain. It will often lead you to not having enough points for the personality you aim for and thus dropping below the required 75%. It is also an extremely long grind if you plan to play everything the intended way, with all matches and events.
If you don't feel like spending a huge amount of time here, there is a method that lets you speed up the process somewhat (although it will still take a couple of hours). You will want to simulate all matches to avoid an unfavorable personality points distribution and earn points through training, decisions, and buying items. The last mentioned way is not super effective as items cost quite a lot and do not give a ton of Personality points, but making investments in the background might make this path slightly more enjoyable and less boring.To get an optimal setup, you will want to create a custom player (or edit an existing one). Go to Settings > Create Player / Edit Existing Player.

Your player ideally matches the following criteria:

• No national team matches (you want as few matches as possible). A player from A-league (Australia) is a good choice as it also does not have a lot of matches during the season.
• The player is a goalkeeper. For a goalkeeper, we can set up up to 4 trainings per week, which yield 160 Personality points.
• All stats maxed out. We want to set up all 4 trainings for an A mark, which will be easier for a player with 99 stats across the board. 

Go to Career Mode > New Career > Create a New Player > Real Player and select the player you created. Then you will need to set up your training plan that will be the main source of Personality points in this method. For a goalkeeper, we will focus on the Virtuoso personality.

Go to Training and do the following four trainings:

• 1-on-1 Against Striker (45 points).
• PK Against the Keeper (45 points).
• Keeper Pass (35 points).
• Deliver Into the Box (35 points).

Luckily you only need to do all this once - but it's important to get an A mark on all of them to get the maximum points award. From now on, you can simulate all trainings every week, and you will get 160 points every time, as simulating yields the maximum grade you previously achieved. Here is how the setup should look like:



BOOSTING UP THE PROCESS EVEN MORE
Additionally, you can try and play one match at the beginning of the season, focusing on getting as many Virtuoso points as possible (by selecting the right enhanced objective). Afterwards, simulate a match and see if you're given any personality points.  If you're given any personality points, you can simulate all matches until the end of the season, and you will keep earning the same number of points every match for the remaining of the season. They should earn you around 2-3k points per season. You need to monitor your Personality percentage at all times however if it doesn't go below 75% for Virtuoso. This is an optional way to speed up the process as it can be somewhat risky if your first played match doesn't have an ideal Personality point distribution.

From now on it's mostly the following schema: simulate a week in the calendar, simulate training, make decisions that give you Virtuoso points, make investments, and then buy items that give you those points as well. Rinse and repeat. As long as you keep an eye out for your Virtuoso level not dropping below 75%, it is also good to earn points for other personalities (buying items, making decisions) as it will speed up the process.

Unfortunately, there is a pretty common bug that makes this effort even longer and sets the bar for Tier 3 personality to 90k points. What's even worse is that it seems to be random, and can even happen during an already started career, as was the case for the author. At this point, it's a matter of luck or waiting for EA to solve this. Once you hit the threshold for Tier 3 visible in the My Star > Personality tab and your selected personality type has a level of 75% or above, the most grindy trophy in the game is yours.
