What do you wish you knew when you started down the path of buddhism?

This stack exchange actually lead me towards the path of finding a lama and becoming a Buddhist. Thank You! This got me thinking, what would you tell sentient beings new to the path of Buddhism? Is there something you wish you knew when you started down it? Conversely is there something that could've been better explained now that you have been pursuing the path? **EDIT:** Given the great responses thus far I want to open this up to all forms of Buddhism. Not just Tibetan, I think there are valuable learnings in all approaches.
