How do I decide on whether to pursue a master's degree or a doctorate?

I am a geology major with a climate science minor and it seems like I don't need to pursue a master's degree before a doctorate. Is this frowned upon, or a good option?

I am exploring my options, thinking about being a vet or something that relates.

I completed my medical school and did 1 year internship in tertiary care hospital outside US. Highly interested in working somewhere related to my field. I am a student of PMBA with major track as healthcare marketing.

I am a junior in high school and this has been my most recent question.

There are so many options, how do know what I go into is going to be the best fit.

Do I have to invest into thousands to become a known hairdresser? How do I gain my clients ? How do I promote myself? How do I get myself into feed and be known for hair

If you had multiple things you wanted to be, how did you decide on what you wanted to be? Because I want to be multiple things, but I just don't know which one I would would want and like best.

I'm currently a third year in high school and still lost on what path to take to get to a computer science degree or in similar area. I feel like it might be too late to correct my path I've made without thinking.
