It's a lot easier to go look for meaning once you have a solid financial base.
I will agree - if you are having trouble making rent and keeping food in the fridge, you're probably not having a very good time looking for meaning in life.
But do you really need to maximize your income? Do you need a $300K job in finance or a $120K job writing code?
I also have a degree in history, so I did pursue liberal arts at the same time. But I knew that wasn't enough for a complete life, in my case.
It's hard to realize that happiness is everywhere, even in abject poverty, when you are financially comfortable.
It takes a lot of effort and a unique mindset to change momentum when you're on a successful trajectory; you're less likely to take a risk to discover a more meaningful life.
You will make connections and develop a lifestyle that keep you happy and comfortable enough that you will not want to make a change, even when that change would eventually be for the better.
Life will happen. If there's something you're curious about or otherwise want to do, why wait?
