Firstly  ,

.which imaginary world do you want to go into?

1.Why do you want to go into that world?

2.Whom do you want as your friends or patner in that world?

And after answering these questions ask yourself, 'why ?'

For the first question the possible answers according to me are because of its aesthetic, because of the people , because I can live as I want to.

If you want to live in that world because of that world's aesthetic look around yourself, think , can't you see any thing that matches that aesthetic?

Remember when you were young seeing these type of things used to excite you alot!

When something thing excites you for example when you're telling you friend about something that you are really excited about that you are almost out of your breath that shows that you are going in the right way!

For second question why do you want that character as your friend ? Because of their behaviour? You think that these people in real world are not really that good or they can never be trustworthy?

I don't disagree with you because I've experienced so many betrayals in my life so many fake friends but now I always hoped for best and have a bestie I share all secrets with and love talking to!

Friend circle is a major thing in our life so chose your friends wisely even 1 good friend is enough to lead life happily but having no friend is better than having bad friends 

Remember you never NEED friends you are enough for yourself!

Do you think the people in that book is really good ,kind that these real people will never be?

Did you ever try to be kind be like the person you wish others were?

Now try it, it feels really good it is what others called romanticising life!
