Code your own damn stuff!

I am building a RFID and button controlled music player for kids.
I am using a couple of different modules for that. The one for the input was really laggy. I thought it was so laggy because of the network delay. I tinkered with it a week but it didn't improved. So I just coded my own module which was much easier to do than I thought.
It was a really rewarding to code something yourself in less than a day instead of trying to get something working for a week.
