Although I cant speak for myself, I dont think this is a universal feeling since my friend exactly wants some one to guide her through. Alone, its easier for her to get distracted and bored but when someone's calm voice guides her through the practice, she can focus on breathing much longer.
If this works for her, that's amazing. There is no one true way to practice meditation but I always suggest people to start with the simplest way. Techniques come and go, the key is still maintaining the discipline to practice it.
Joining a community of practitioner is also very beneficial - this is how in the Buddhist traditions meditation is taught and discussed - however it's not always possible depending where you are.
Meditation though is not a silver bullet. If it works for you great, if it doesn't benefit you, move on.
