I want to expand on the idea of the easy way versus the correct way. The way you play and sing right now is what's natural, automatic, and feels right. Most new techniques will require you to do something different, which will likely seem unnatural, forced, and awkward. You need wisdom and frequently good advice (insert awesome teacher here) on whether a particular thing you're trying to do is right, because it can be hard to tell whether a particular technique or way of doing something is right based on "ease" and "nature" alone - because you can't necessarily see the outcome of it. While it's very, very true that in many areas of music technique we want what is natural, ergonomically right for the physical mechanism involved, often what is "easy" - that is natural right now, in our inexperienced present, is not what's best in the long run.
Perform in present tense, what you do well, rehearse to make it so. Practice in future tense, what you will become, reach out to perfection.
