It's important to respect that, while you are important to your friends, they also want to see what their other friends and family are posting and doing. So don't overshare the lives of others.
You can think of it like being a part of a group conversation. Everyone should have a turn to talk. Don't dominate the conversation.
It can be tempting to wake up in the morning and share a few dozen things that made you happy, angry, or sad. Do everyone a favor and space out your posts a little bit.
Don't worry, I'm sure your friends love hearing from you.
