This is what the path of Dharma is like. It's not that you have to do all the practices. It is sufficient to take just one of them, whichever one you really have an affinity with, and through practicing that one alone, for the rest of your life, you will achieve enlightenment. Whichever practice you choose doesn't matter; they are all valid methods for achieving enlightenment—if you practice. The key is to practice with diligence for the rest of your life.
