I worked a finance day job and a supermarket night job. I've saved up nearly $300K toward early retirement.

Ryan Lowe lives with his parents in Massachusetts and recently worked two jobs.

The 27-year-old wants to retire in his 40s and spend time traveling.

This as-told-to essay is based on conversations with Ryan Lowe, a 27-year-old living in Massachusetts who shared documentation of his savings with Business Insider. His words have been lightly edited for length and clarity.

I want to retire early . So I tried working two jobs — an office finance job during the day and as a product sorter in a grocery store at night. I also live with my parents and drive a 20-year-old Toyota Camry.

I'm 27. I don't drink, I don't smoke, and I don't go out to parties. My parents buy the groceries. A lot of people would look at my lifestyle and say that I'm a bum, and they're not wrong.

Over the years, though, I've saved up nearly $300,000.

I get paid between $1,100 and $1,200 every week from both gigs, and I usually put $1,000 of that paycheck into the S&P 500. It's a very safe long-term investment. If that were to crash, then we'd have bigger issues than my retirement fund .

I'm hoping to retire in my 40s and spend time traveling. When I'm not traveling, I want to have a chill, quiet lifestyle — just like I do now.

I quit my job at Stop & Shop three weeks ago.

I wanted to stay, but the time I spent commuting was starting to add up. I also didn't have time for important things, like working out and eating good food.

I loved my job in the grocery store . It was just me in my own world, and it was as easy as it gets. The managers were usually gone, and they would leave notes for me.

I previously had another grocery store job at Whole Foods. That worked because, at the time, my finance job had a hybrid schedule.

Now, however, I have to go into the office in Boston every day. I work in East Boston, and I'm salaried, so I'm limited to 40 hours a week no matter how much I want to work. For a whole week, I was spending 12 hours commuting on the Mass Pike.

I recently went on a trip to the Italian Alps, and while I was there, I was thinking to myself, I don't want to go back to doing that with driving every day and working two jobs .

I'm looking for another side hustle I can do at night — hopefully something that pays more than minimum wage.

It's important to strike the right balance.

Ever since my high school days, I've been really busy, working extra jobs over the summer.

Sometimes when I'm just sitting around, I think to myself that I could be making extra money.
