To respond most directly to your question "What am I doing" collecting Wongs if I don't intend to/am not able to do the meditations afterwards?

It is natural when we begin to realize the responsibility of the student, to feel daunted. We attend a Wong feel the "lift" given by the power of the ceremony, and try to complete 10,000 repetitions of the mantra in the next two or three days.
Then we learn we are to repeat 100,000 of these mantras!
Up comes the negativity: with my life I certainly won't, no way, not able, too busy, don't want to dedicate my life to etc etc etc.
Watch the negativity. That's all it is.
It's just a state of mind. It's not the truth, it's not what is important and you certainly don't have to believe in it.
It's just a state of mind.
Then ask yourself what happens if you just keep repeating a few mantras, a few rounds on the mala? What happens when you feel/ are aware of negativity and begin a few rounds of the mala, say, three?
Watch what happens in this case.
If you keep your view on the footstep you are taking right now, you will surely have a more exciting journey.
Don't be daunted by apparently large numbers; start where you are.
The old saying applies "the journey of my life started with the first step (proceeded with the next and the next)"
