Okey, I am not that person that has lots of lifehacks. 
The best advice that my granny told me - if you want to stay slim, eat green salad before the meal. It will improve your metabolism and you will be young forever.
Also, I heard that using flour and hair dryer you can "wash" your hair. Flour just absorbs all the "fat" from your hair and they looks fresh. Honestly, I have never tried this hack.
From the childhood I remember that if you accidentally have caught chewing gum on your clothes, you can put it in the deep freeze and after hour you can take is out and you could easily take it away.
Really useful hack is related to the high heel shoes! My classmate told me one very simple trick what you can do if shoes doesn't fit you (if they are a little bit larger than your feet). You can use double-sided tape and just stick your food to the inner sole! Voila.
