On the contrary, if you have goals and aspirations in life, by all means start planning NOW to meet those goals! That doesn't mean that your goals won't change, or some of them may even go away completely in the process, but it does mean that you have a plan for your life. And a plan means that you have a way to get where you want to be.
Personally, I think planning two years in advance is nothing, I currently have an 8 year plan which includes graduating with my BSN next year, maybe having a (probably our last) baby, getting a couple of years of critical care experience in and going into a doctorate CRNA program.
I am doing what is necessary now to meet those goals (such as keeping a high GPA due to competitive programs, paying off bills now in preparing for not working for three years). I'm also doing my honors projects on anesthesia and when I do my internship, it will be in an ICU. I do research on CRNA at least on a weekly basis (including here at AN, online & print books). I'm soaking up all I can because I find it fascinating, at least in between NS & family
A plan is a great thing to have, but IMO, it should also be dynamic and flowing depending on your current needs.
Of course, I'm a little older than most (32) and I'm driven, ready for success and have a family to consider in everything I do
We'll see how it plays out in reality though, my plan may very well change.
