I keep my life as simple as can be, more or less I dislike complexities and I always say what's on my mind without being rude. Although these are tips regarding hobbies, I think generally it's a good way to keep things as simple with most things in your life. I don't think it's impossible, we just have to get rid of the lies and negative feelings.
(Easier said than done perhaps, but it's better to try than sulk about being miserable I say)
We love things to different degrees, from our friends to types of food and to the things we spend time on. It kind of sucks that there aren't a lot of people who are open minded enough to STOP ARGUING about how to look at things. If someone doesn't agree with you, just RESPECT them and move along.
So honestly, I hope that in a hobby as creative as cosplay we have a lot of more people who are much more accepting. Having a debate on who's right ONLINE will not help you earn money or finish your homework. Technology has changed vastly, but you still have only 24 hours in a day. So SPEND IT WISELY.
