I think it's been 8 months since I've deleted my instagram account. It's only had positive outcomes on my life. I found I was on it a bit too much. Yes I don't see what everyone's up to and the pictures they post, but it's not a big deal! After all, instead of staring at my phone when I'm with people I try to make conversation.
Here were my 2 major reasons:
Narcissism
I noticed a lot of people were taking selfies including me. I mean yeah they looked good but it seemed like I wanted to show everyone how good I think I looked or something. I wanted people to tell me how good I was, not wanting to hear it from my own lips. I started posting only group pictures before I deleted it to make me look like I had more of a life than people staring at their reflection. Ultimately I realized I should be lifting others up instead of trying to climb to the top.
Determining Worth By Likes
Like everyone I was always excited by how many likes or comments I'd get on a photo. If I didn't get what I wanted I convinced myself it was quality over quantity and if that wasn't enough just delete the post altogether. When other people would get more likes and comments it'd bother me. I was spending too much time checking my phone for a new notification after I read my quote over and over and over before posting it. It started occuring to me that none of this mattered and I should put my focus on other things. So that's what I did and I haven't looked back. Mind you Instagram doesn't seem like that big of a deal, which it's not IMO, but it can lead to other things improving your life.
I don't care whether you keep or delete instagram just don't be a narcissist or determine your worth by likes.
