Do you think my sister miss out by not using her full potential to the fullest?

She's now 28 years old (older than me by 3 years) but she chose a normal life. If she wanted to she would have become a chess champion; after all she beat a great chess player when she was only 12. Though she never treated it as a competition, just playing for fun. She was always advanced for her age since her toddler years. Her current IQ reminds the same, 162.

She had several grades skipped, graduated from HS at just 13 years old, went to college and finished earlier with her degrees than others. She was a marine biologist (she's putting that on hold for now and dedicating on motherhood) but then focused on having a normal life, getting married and having kids. She placed her childbearing years as a priority.

She got engaged at age 23, married the following year and became a mother at age 25. Then got pregant last year. When me and others questioned her on why she's not using her full potential, she said she already use enough during the early years and said there is no point anymore and she doesn't want fame and hates publicity. Wow. She could've earned more money.

Do you think she still miss out?

Instead of using more potential, she gets pregnant again last year. Now she's a mother of 3 kids; a girl on the first pregnancy and twin boys on the 2nd pregnancy.
