What is a good scientific field to get into for a 21 year old university flunking midwit who besides watching popsci videos has not seriously studied science since high school?

It can't be too challenging since I'm a midwit and also I want to look at pretty things. Was thinking astronomy but it's too cloudy where I live so maybe geology? I'm fine keeping it at a hobbyist level but anything with a potential for employment is a bonus.
