I recently saw a book whose title (in German) was "Life doesn't gave a reverse gear" ... which simply means one cannot go back and change things. But you are young and have many decades left which you can use to do what you now consider worthwhile. One last tip: even if you now plan to do better with computers, always try to have a hobby away from computers. Or else you might someday regret that you (again) spent too much time in front of digital devices. Using certain devices outdoors is ok though IMHO, for example at photography (digital cameras) or geocaching (gps).
