Uncomfortable beginnings...
When we start something new, especially something that we want to do or something that would make our lives better, the beginnings are more or less uncomfortable.
When you start a diet, you may gain a kg or two in the first couple of weeks. When you start reading, you might start feeling less competent than when you started to read. When you start introducing yourself to new people, you might feel more awkward than when you stayed by yourself.
This is part of the game. The beginnings are uncomfortable.
But that's just the beginning part.
Once you get through the initial stiffness and muscle pain of lifting weights, you crave more of it.
