Day 396 - You pay for everything thrice - https://golifelog.com/posts/you-pay-for-everything-thrice-1643584305086

Every time you buy something, you’re not just paying for it once, but thrice.

• Upfront costs: You spend the money purchasing it.
• Opportunity costs: You spend time and effort to set it up, experience it
• Maintenance costs: You spend time maintaining, cleaning, updating it to continue using it

For example, a new online course on Coursera:

• Upfront costs: You pay $100 for it.
• Opportunity costs: You actually make the time to do the course, learn and benefit from it
• Maintenance costs: You got to apply it, use the knowledge
