It is never too late for education. It is always too early for crippling debt that exceeds your proven earning potential. None of this advice touches on the lost principle of not putting one's future on layaway. Student load debt forgiveness is a death sentence for American politicians yet there are millions of us waiting for a miracle.
The "best" college educations typically take 4 to 10 years to reach a break even point. Some degrees can result in a net loss of lifetime income.
The older you get, typically the less monetary sense a degree makes. Couple this with an open admissions degree from a for profit college and you are likely on thin ice.
If you (as a returning adult) want to continue your education, that is great. Just make sure you are doing it for the right reasons.
