Yes, the most important thing is not to rush.
Look at the instruction, understand what you are doing, look again before you solder, make a good joint and then look at the instruction again to verify.
The worst thing is you turn it on and nothing happens.
Well, that's not as bad as turn it on and the fuse blows.
No wait, the worst is you turn it on and smoke happens. Yeah, that's the worst.
And fixing it takes 3X (or more) time of building it.
So, don't rush -
