You might burn yourself out early, but if you stick to it then it should be hard to get burned out in the future. For the first few months, you'll spend a lot of hours into the game trying to do everything you can with the limited charisma/stamina pool. When you have played for a long time, then you'll only need to spend less than 30 minutes a day doing whatever event is available and then wait for the next day to do it again.

The only time I'll spend hours on this game on one day is after maintenance when a new event happens because of the new and shiny content or when I need to farm one mission a lot. Having 427 charisma and 18 stamina cap does help a lot.
