The day you start feeling what you have was owed to you. Or it is just the result of your hardwork. Or that you deserve it.
That’s the day your downfall will start.
Nothing is owed to you. Everything you have or will get in future is a blessing. Being grateful and passing it forward is the only way to sustain it.
Your work is your duty. Give your 100%. That’s your karma. The only thing you control. Stick with that.
