This article can help you to check things that you should pack before travel. It is basically prepared for man but with smaller corrections could be applied to woman too. Feel free to add on list with comments.

How many times you started to pack yourself night before trip. And you always had feeling that you miss something. Because of that I wanted to know how many things I need for three day travel? Three day travel consider two nights. I didn't know so i start to list them:

1. socks (two pairs are minimum depending on time of year and what shoes are you wearing)
   
2. undershirt (two pieces, it should be same colour, preferable white to match all shirts)
   
3. underpants (two pieces minimum, your choice)
   
4. pyjama (one piece, model that takes less space in your bag, if it is summer time you can even use your underwear for sleeping)
   
5. spare shirt (one piece with universal colour, light colours. Option is to not take spare one but have option to buy it (in store like H&M) in case of emergency)
   
6. toothbrush (look for travel models, in better hotels it is always possible to ask for tooth pack on receptions)
   
7. toothpaste (also check small travel packs, same as 6)
   
8. deodorant (any kind, not in glass pack, roll on is good choice)
   
9. shaver (use your standard one, also it is possible to ask on reception for shaver pack in better hotels)
   
10. shaving foam (use your standard one, same as 9). Instead of shaving cream you can use soap.
    
11. recharger (for all kind of mobile devices, depending of quantity you have desirable to have universal one. This days it is mandatory.). If you have many devices you can use universal one. Check before is there connector for your gadget.

On your trip wear clothes that can be used in any occasion, business and casual. Take bag that is "Cabin baggage". You will save some time on airport and you will much easier handle your baggage.

If you are regular traveler then check on airport travel sets for hygiene.

And I found number. It is only 11!

(Even less if you use hotel tricks)

Of course this number is related to male travel. For woman I suppose the is much longer. Maybe you can write list of female things for travel?

I know it sounds strange but how many times you forgot to do something. Like feed the fish before you went on holiday, or when you forgot your lucky pants?

If you once write down everything you need for regular travel, next time you will save a lot of time and you will be sure that you packed everything. And much less stress.
