Don't plan it out too much. You'll end up driving yourself crazy.
You're only 14. Chill. Live out high school, go to college and get a degree in anything other than aviation, and continue to build time. Buying a cirrus as a low-timer is ludicrous. If you must buy a plane (risky investment), get something older and easier to fix.
Like I said before, planning ahead is good, but don't drive yourself crazy with this excessive planning crap. You'll figure it out as you go, and believe me, your priorities will change as you get older.
