Back to the basic rule- "pick the pin that binds"
You want just enough tension to make it a bit more difficult to raise one pin, as you slowly raise that to the shear line, pop, click, snap, whatever, will happen and you will find a new pin binds, repeat as necessary.
A couple of tips:
-some pins may actually not need to be set, if you find you are pushing a pin and it keeps going up and up, it may need to be very slightly bumped.
-don't make things more complicated then they are, and use a lighter touch, often in frustration we start to try to "force" the lock to open, to make this situation worse, it may work on cheap locks. Thus the invention of security pins. Learn early, a light probing touch will benefit you greatly later on.
-sitting there for hours pushing pins in is not the best way to learn...I think probing into a lock with a pick is a great way to get a feel for the pins, however, take it from me who learned the hard way. Pin by pin picking requires that you know what pin you are picking, what type of security that particular pin holds, what strategy you intend to employ on that pin, etc.
Sorry, I sometimes ramble, I have strayed from and come back to the basic point, which is...pick the pin that binds.
Good Luck
