It's quite understandable that when someone goes on vacation, he/she would like to be as free as a bird. The expression 'as free as a bird' means 'being completely free, with no worries, troubles or encumbrances'. The noun 'encumbrance' means a 'hindrance' or something that hinders you from doing something. So, if you are going on vacation, doing English lessons while there will definitely interfere with your enjoyment. So, you may say to someone: I will not be taking English lessons as from tomorrow because I will be going on vacation for about two weeks. or I will be going on vacation as from tomorrow, as a result, I will not be taking English lessons because I would like to be as free as a bird and enjoy.
