I was frustrated with pushers coming back to tennis after a long layoff. I played 4.0 thinking it was going to be some decent hitters, and it was a lot of dinkers, dropshotters and lobbers.
I lost at first. A lot. For about a year or so. Tournaments, leagues, friendlies.
So I went to my local pro and asked him to give me those exact shots. Over and over and over again. I asked him to give me 50 drop shots in a row, to lob me mercilessly, to hit the ball right down the middle with light pace. I worked on not double faulting anymore, spinning in a serve instead of a huge, but inconsistent, second serve.
It worked. Guys I had lost to previously I beat in straights, easily. One guy who crushed me previously smashed his racket on the ground, breaking it, because he was so mad.
I still play them sometimes, but now I mostly play 4.5 or above when I can. It's a rite of passage, look at it like a challenge.
