I've decided that the optimal path I want in life is $2.2 million dollars, and then to live the rest of my life off of the interest generated from an index fund (approx $80K/year after tax).
Right now I'm in college studying Computer Science, and in my free time I write (I'm not any good at either yet, but now's the time to get good, so I'm not worried).
I've thought about a start-up, but the risk and reward are both too high. A successful startup is around the $10 million to $1 billion, depending on what you create. This is way over my goal. I'm sure the risk is proportional to the potential money earned, so it'd be inefficient to overshoot my target.
It's very rare for you to meet someone serious about saving money. Before you know it, they're complaining that you never do anything even though you have plenty of money (relatively).
Are you sure you won't want a relationship? You're young enough that within a decade you'll be a completely different person. It doesn't seem that way now, but a decade is a massive force.
There are other things you'll be giving up: Pets, for example, are quite expensive. Sinking $3k into an electronics hobby is also rewarding. You'll also be buying everything second-hand if you're really serious about saving, and it's hard not to become frustrated with all of the poor-quality things in your life.
And then before you know it, your youth will be gone. Time is more valuable than money.
Just think carefully about your goals. It's easy to set a lofty aim, like becoming a doctor, and then set yourself on a trajectory you may regret.
