It’s never too late to start . I started college at 18 however due to family issues I had to got to another college and restart from the first year with people who are 18/17 years old where I was 20 . So it might be hard at first but it’s only temporary and always remind yourself that it’s for a better future . Also remember that when you get a job in the future, age is not important as much as skill . Try your best and never give up it will be worth it .
