Everything Else is Everything Else.

Things you should definitely pack if you're travelling to a new place(especially mountains):

• Sleeping bag,
• Money,
• Mind open enough to accept changes,
• Knowing the fact that the people you're about to meet would probably have a very different lifestyle than you and you should be a little considerate and sensitive towards it, 
• Clothes,according to the weather,
• The excitement of exploring a new place,
• Camera, and probably an extra memory card,
• Desire to make new friends and carry those friends in your camera roll,
• A little selfish attitude to click as many silly stupid pictures as you want of yourself or your surrounding because you won't come back again for sometime,
• Knowing you would get scared for the first few days,
• A notebook to write/draw all your thoughts/emotions in. You probably won't feel the exact same for any other place,
• Music,
• Acceptance of the fact that you'd probably get lesser sleep than your daily routine because you wouldn't want to leave the the streets till after midnight,
• The feeling to not be a tourist but live as a local of that place.
• If anybody tells you not to go, you should probably go anyway,
• Other materialistic thing.
