Do good deeds and you will always feel good about it. Even if someone else used you in some way.
Share what you know. Don’t use the text of someone else.
You can’t be good in everything, but you can sure be good in a few ones.
Use the good to make some good post.
“Be content with your lot; one cannot be first in everything.”
There’s no need for you to go outside of your comfort zone. But sometimes, you could expand your knowledge and develop a larger zone.
Learning is the fountain of youth.
