We all have hobbies. We all like to do different things in our spare time and we can pick up new hobbies from the people we are close to, as well as people we aren't so close to. Some hobbies are forced upon us, and others we choose to do.
Sometimes, friends can pick up on our hobbies, and that CAN be a great thing, but I'm going to highlight the things that good and bad within a situation like this, from the perspective of the person who has picked up this new hobby, and the person who has had this hobby longer.

You have someone to share new ideas with and talk to about your hobby with. It means you can get alternative views and bounce your ideas off someone. This is a great time for you to share your knowledge and help out someone new, as well as allow you to go over the basics. Just remember that it doesn't matter what they do, and that it's still your hobby too, so you don't just have to help them, you can carry on doing your own thing. You don't have to share all of your ideas with them, you can still be independent. It's also great to get a beginners look on things. Sometimes it can put things in perspective.

Congratulations! You have found a new skill to pick up, and you have someone to help you out along the way at the beginning. This is great because you can have someone tell you the apps/supplies/techniques they find best for their specific hobby. However, remember to be your own person. You don't have to do everything the other person does. That's not how it works. Take it in your own direction. Don't do things the other person has said they want to do or has done just to spite or keep up with them. It's not a competition and if you enjoy it then surely that is all that matters.
Hobbies are a great thing, just make sure that you are your own person and never do anything you feel forced to do. If your parents are forcing you to have piano lessons even if you hate piano, ask them to sign you up for something else like are classes, guitar lessons, or even how to code a video game. Everyone is great at something, and if you haven't found what that is for you, I'm sure you will.
Have you found a hobby you enjoy? Have you ever picked up a hobby off of a friend or vice versa? Did any conflicts arise because of this? Let me know in the comments
