I wrote down in my diary - earnt $20 - sacrificed 2 hours of sleep, 2 hours of not watching netflix and put in mental effort when mentally I was exhausted.
there is a problem with what you wrote, I will explain using this:
Now when I would have the urge to gamble with that $20, I would just see the diary and would realize I am not just gambling with $20 but gambling with that sacrifice of time and effort which I'll never get back. And it has worked for me to a certain level.
what happens if you lose $20 because of gamble? you will start to get depressed and you may risk committing suicide. Many times in life when we take some things very seriously we start to charge ourselves in an exaggerated and excessive way
you will not accept that you lost $20, everything you see in your head Is that you lost $20, money that you earn of a lot of sacrifice and with that you will punish yourself for a long time
See, making money has never been easy for anyone. People work 8 hours a day for 30 days to earn a salary. Entertainment is a right that people have, you can take a small part of your salary to drink beer, to drink a good wine or to place sports bets. But don't be charging yourself too much
What's your opinion on this......
enjoy life as much as possible, don't be thinking things like: "my god, i lost money i earn with a lot of sacrifice". Don't think like that, make an effort to make money, but also have fun with the money you earned
