I think everyone want to have their own planet because sometimes we feel isolated from others , neglected from someone we care or sometimes we merely bored this world. So imagine if we can make our own planet that no one cannot interfere us, it may be a good idea but could it bring us to literally happy?
If I had my planet, If I have my planet, I will create it with my heart .To elaborate, I will make a small village on my planet where is everyone admires each other as same as themselves. There is no extravagance
