saving for my birthday

so I have done a lot of thinking, and I want to go kayaking for summer during my birthday. I am going to start saving money from now, and take a week or less off. I want to go to La Jolla and stay in a hotel/motel, even if I have to do it alone. However I also need save money because I will not have enough money for summer, I need to find a better paying job with stable hours.
