Firstly, a good attitude is a MUST. I dont know what sort of seminary you are going to, but be prepared to take EVERYTHING with a smile. You probably will need some time ot adjust, and there will always be many girls who will complain about everyone and everything. Do yourself a favor and consciously plan to look for the best in your situation.
It also helps to be super friendly for the first few days. Be the one to introduce yourself–to girls and staff. Be the one to help out another girl who lost her luggage/forgot to pack something/ needs a shoulder to cry on. First impressions are important, you want everyone to perceive you as sweet and friendly, and not immediately write you off as “not for me” (thats what girls tend to do, but you shouldnt do that!) And the staff will absolutely love it =)
Also, to make the most of your experience, you have to have the proper mindset. You probably won’t feel a sudden rush of emotu=ion everytime you go to the kotel. You need to for the connection.
Every girl that comes is feeling a bit lost, even the girl with a hundred friends and a blackberry that never stops buzzing. Just offer a smile and kind word, and you will be loved, and well taken care of.
Good luck =) Israel is a beautiful, wonderful place, and seminary is ayear to learn a lot about yourself!
