Be open to spending some extra $$ on comfort--seat especially. I'm not saying buy an expensive seat right away, but if after a few weeks, it is not comfortable, first try adjusting it forward/back, up/down, then try something different. Same thing (to a lesser extent) on the handlebars.
If you are comfortable, you will keep it up. I had an expensive bike for years that was uncomfortable, and I didn't ride much. Now I have a cheaper bike that I am comfortable with, and use almost daily.
