Yes, and you have to have faith in what you want to achieve.
The creator warns not to wish/visualize anything negative for other people while using the audio. Because it moves a very powerful energy that could make that bad thing we ask for, happen to us.
(I know it sounds scary, but it’s not the nature of the audio itself, but something that could happen if we have negative intentions).
If you want to use something a lot shorter, you could try Remove Obstacles - Om Gam Ganapataye Namaha mantra from Spirituality Zone channel.
