Problems with packing?

Have anybody got the same problem like me?
I don't know why I always have a problem with packing everytime! Actually,I do know why.... :(

I am not really a backpack kinda person.
What is backpack kinda person? Well,someone who can just go anywhere with only one small backpack, no booking anything in advance.... or someone who can even camp in a tent! That is absolutely not me!

When I have to go somewhere, I feel like I need the whole container transporting everything together with me! I want to be so adventurous... but I do not see myself like that in the next 50 years! :P
