If you are a tennis pro, you should love your job. You really need to enjoy it to do a good job. A lot of it is how you relate to your clients.
In finance, if you don't really love your job you can still work hard and do a good job.
Go get a finance job.
ps. No one who has a job easier than a coal miner has a dirty job. We can do without tennis pros or finance majors, without coal miners society would completely fall apart.
