How do I tell if my wanting for transformation is wholesome or greed?

Sayadaw: Not every desire is greed. You have to check if the wanting is motivated by wisdom or greed. 

If the desire is wholesome, the mind feels confident, purposeful, clear about what to do and works towards its goal.

Once greed is involved, and greed has its characteristics, there are impatience, tiredness and boredom with the practice – all these signs will show that greed is there. There is also dissatisfaction or tension when greed cannot immediately get its goal.
