Life happens as it will.
We can exercise, travel, make plans, have an agenda...etc and so forth BUT we don't have total control over the way things play out.
Having said that we do have some control which is up to us to exercise it.
As to life not always playing out as you want; I don't think that's all that unusual.
My mom said, after my dad passed on, "where did all those years go to? It seems like just yesterday that we began our lives together".
Time is what we have on our hands today and tomorrow. It is not easily understood as we look back. So we look ahead, taking the lessons we remember from the past along with us.
Doesn't all the life you lead in the past seem small when you try to measure it

.
Live each day for the day it is. The 'rest of your life' is what happens from this moment on. Look for interesting things that you enjoy and if it's not housekeeping than do the minimum and get to the stuff you like.
