“I have lived the rest of my life very responsibly, living within my means.

I’ve invested the max in my 401k.

I buy used vehicles and pay them off as soon as possible.

A serene, empty brick arcade with arches and columns, leading to a view of greenery and trees outside

The wasted money comes from something I know is bad for my health in the long term.

I have to admit, I have little control over it, although I keep trying.

So, any of you younger folks here, take it from me.

“Loaning money to friends.

Or anything of financial value, for that matter.

Modern row of urban townhouses featuring varied brick facades and large windows, under a partly cloudy sky

That saying about loaning people money is true.

That has happened to me every single time.

I will never loan money or things of monetary value ever again.”

“My first trip to college.

A peaceful lakeside scene with a dock jutting into calm water. A pot of flowers is placed near the dock. Trees and houses are visible in the background

I racked up $56k in debt, and I dropped out.

The cost of campus housing was more than the tuition, and the program was garbage.

The school later lost its accreditation and went out of business.

Side view of a car with a "For Sale" sign in the window. Suitable for an article on selling a car for extra income

That was the worst decision of my life.

Not just financial, as the collateral damage was also severe.

I experienced depression, which assisted with the loss of a job and loss of relationships.

“In 1991, my then-wife and I were looking for houses.

We found one that was 2,000 square feet and lakefront.

The house needed repair and was a repo with lots of water issues.

I am a carpenter; in 1991, I was still an apprentice.

We bid $65,000, which was the only bid they received.

She worried that we couldn’t afford it.

I think I was making about $13 an hour at the time.

Fixed up, the house would have brought $200k back then and probably $500k today.

It wasn’t that bad; structurally, it was sound.

And we both loved to fish.

It’s easily the one that got away from me.”

I lost about $7,000, which isn’t the biggest issue.

“Much later in life, I made a bet with someone about the outcome of a book.

I lost the bet and transferred one Bitcoin to a stranger online.

This was when the price of Bitcoin was in the $6,000 range.

Both setbacks felt like huge deals at the time.

But neither was as big an investment as my latest car or the house I’m buying.

“Not moving on to a higher paying job and taking that leap of faith.

“Turning down a $40k scholarship because my mom wouldnt let me visit the college.

It was my dream school.

I transferred there with a $4k scholarship they offered.

If I had taken their initial offer, I wouldve only had maybe $10k of student debt.

Now Im $55k deep.”
