It seems like cold approach takes a really long time to learn and you have to deal with a LOT of rejection before being able to get even decent results. Is it even worth one's time to do so, especially for those of us who have somewhat limited time working full time and going to the gym every day? It's also come to my attention that PUAs may push cold approach as the end all be all just to sell their products, so maybe it's not worthwhile.

Thank you!
