Okay.
College - Graduated high school in 2005. Applied to one university in my home town. Decided I wasn't sure if it was right for me. Went to a junior college. Following that year, decided I might like a school in the bay area. Went to that school. After a year of it, decided I didn't like it and might like somewhere else better. Went to a junior college again(third year of deciding), and am beginning my fourth year at another university. Except this time I can't change since I've done it so many times. I'd be wasting my time if I transferred again. So... all in all, it has been 4 years of college to finally decide on a place to go.
College Major - Because of all the thought about my future career, I felt it was paramount that I have the right major that would suit me best. First year it was Biology. Just basic Biology that was on the pre-med prerequisite route. Second year, changed it to Molecular Cell Biology w/ Chemistry minor because I thought that I would be better prepared for medical school. Third year, switched it back to Biology. Fourth year, changed it to Kinesiology with plans to be a physical therapist because I believe I would be most happy with that. So four years again.
Relationships(I consider this to be a big decision) - I consider it to be a big decision because I take relationships really seriously, and when I commit.. I really commit so it must be the right person. I make sure that I know the person really well, and make sure that I can hang out with them without getting annoyed/being annoying. This process is between 6 months to a year. Then after that, I decide that they are dating material, and if they stuck around that long, it must be worth it. And shortly after that, possibly move on to the next step etc. So that's a rather long thought process for a "big decision." And PS, during this time, I'm always analyzing the person and interpreting things they say and do and calculate that into whether or not they are the "right person."
Jobs - I purposely worked at several different places to see where my niche was before making a more absolute decision. I tried several different jobs and endured them for at least a year, whether or not I liked it. I tried the UPS store for a year, tried the office "cubicle" job for a year for the state, worked at Starbucks for a year, sold on eBay, and so far none of those have worked out for me. Easy jobs, but it becomes mundane quickly and doesn't cater to my personality. I found that after two years of tennis and being in the athletic training room everyday for my injuries, I really liked that environment... being in the physical therapy department. So that took... 3 years to decide on that. And because I experienced the other jobs, I'm not going to feel like I missed out on other opportunities. I feel like I'm making the right choice.
Purchases - I do EXTENSIVE research before I make any "expensive" purchases. Before I bought my laptop I kept second guessing myself about which one to pick out. Surf the net for reviews and prices daily, hoping that I find out something new. Before I got my laptop, I literally surfed the net for reviews and forums about every model for nearly 9 months. I wanted to make sure that I didn't pick the wrong one and regret it, wanted to make sure that I didn't buy one that would break down quickly, and wanted to make sure I got one that would last several years.
When it came to purchasing a camera, surfed the net for 8 months consistently reading reviews. Etc as above.
Hm I can't really think of anything else.. it's 1:36 AM here and I'm sleepy. Any other topics you want to know about let me know. =]
