This Safer Internet Day, there are lots of ways you can personally help to create an internet that we can all have a little more trust in.
Whilst some people on the internet can behave badly at times, it doesn't have to be like this.
And, if we all decide to be better online, we can help change the internet - one post at a time.
Here are some tips from BBC Own It to help you live your best life online - and help to make the internet a place we can explore safely, and celebrate positivity!
Think before you share that meme or write that message - would I be upset to see this? Put yourself in the other person's shoes and imagine how reading a post might make them feel.
The Own It app has a smart keyboard that can help you spread kindness through the words you use, and it helps you to stop and think before sending a message you might regret.
Don't be drawn into arguments online and be kind to each other. Sometimes people are just looking for a reaction, don't give it to them. If it's a disagreement between friends and someone is annoying you, put down your phone or hand it to someone else until you are feeling calmer before responding.
Sharing helpful articles, funny memes and GIFs, and reposting happy, positive posts online is a great way to help others, including your friends. It will also help you to feel more optimistic and happy every day. You can take some inspiration from these Random Acts of Kindness.
