How to pack for a trip?

Have you ever had any problems with packing your things for a trip? I am sure that everyone of us had! If you buy cheap flights with hand luggage, it is even harder to take everything you want. When I was younger I thought that I need abroud everything what I have. Now I know that if I go for a trip I have to organize everything I will need and make checklist of every items I want to take with me. But there is one thing that I always forget, to be honest. My sunglasses! (That's why I have so many pairs) ;)

Another important thing is to plan your outfits for these days. If you want to pack five pairs of shoes for 3 days, you should think over if you really need them. Check the weather in the city you will visit and bring only appropriate clothes. In addition, you should buy travel-size containers for your cosmetics. Remember about restrictions on the amount of liquids (which you can bring on a board) when you are flying only with hand-luggage! 
Don't forget about documents (valids of course), money, your camera and go for a trip! I hope you will have such a good time!

See you soon! :)
