As others have pointed out, it would be wise to seek the services of a wealth manager to handle the large sum and have it in a place which passively funds your lifestyle sustainably.

I would highly encourage you to pursue your passion. Since you are in a financially better position, the desire to just get a high-paying job might no longer apply. The option of applying for positions which do not traditionally pay so are available now well where you think you could really make an impact.
