I'm starting to realize that more and more but I'm having a hard time not asking myself those "What if" questions. In some areas of my life (day to day activities), it seems to me that I have no problem of "letting go of things", but when it concerns big life event, like the choice of my university degree, even if I rationalized my choice before starting university, I'm still asking myself three years later what If I had chosen engineering or philosophy or ... ? Life opens up such a variety of opportunity that I kind of feel tricked by choosing one over the other.

"There are seemingly infinite directions our lives could go in. That can be disconcerting to some, but to me I find it extremely exciting and even encouraging."

That's indeed exciting, but it increases complexity. In one week, I'm going to enter my fourth year of college (in France, university is divided in two parts : the first three years are generally focusing on general topics like economics, management, philosophy, history, etc. and the fourth and last year are more focused) and I will have to decide at the end of the year in what I will be working for a huge part of my life. Marketing, logistics, finance, accounting, consulting, entrepreneurship are such diverse topics that I still don't know which one I'm going to choose. I don't have a "one beats all", I find multiple topics interesting and I think I will be able to have a happy life whether I chose one or the other.

Thinking about it, I thought : well, I should chose something that opens up opportunities where I could have a meaningful life, then I thought, what is a meaningful life ? I then remembered this letter by Richard Feynman : http://genius.cat-v.org/richard-feynman/writtings/letters/problems ""The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to." and it's just an infinite loop in my head. I bought How Will You Measure Your Life ? by Clayton M. Christensen 5 days ago, it might offer me some answer.

Thanks.
