You have to start with small steps before you can run.
Excel is considered by many to be a useful program
but is at heart a program which reads strings and
does simple math. It just does that a lot of times
- once per cell.
A Word Processor is essentially a program to read
in strings and reformat them by inserting extra characters.
A database stores data in files and searches for it
And most user programs (as opposed to servers) are
essentially variations on those three themes.
If we add manipulation of images and sound (which admittedly
are more complex) and some basic networking(email/browsers)
then you pretty much have the average PC users ambitions covered.
But you have to understand the basics before you can put
them together. Its likelearning the chords on a guitar before
being able to accompany yourself, or composer a new tune.
The better you grasp the basics the easier the more advanced
stuff will be later.

Stick with a tutor and adapt the examples as you go. Be sure
you understand what your changes did diffeently and why. As
you keep going the examples will get bigger and more "real world"
