Time is Money
When you first start out as a developer you find a problem and build a solution. This is how you learn and progress.
As you become older your outlook changes and you’d rather pay money to save time. Of course, you could still build it, but eventually, you hit a tipping point.
Developers are some of the worst offenders of this problem. We have a problem and spend lots of hours building or own version when we could become typical consumers.
To give a real world example of this, I decided to create a weekly newsletter and instead of paying monthly for a service I did it all myself.
After a few months, I realized I was spending close to five hours a week just getting it ready to send. I then switched to a paid service and it cut my time down tremendously. I could then spend the hours saved on more important things.
