Let's not ever forget that while this work can be a lot of fun, we still need time away from it. If you have a family, make sure they are being given the time they need. Burn out, even from something you enjoy, results in a detrimental impact. Getting enough rest, sleep, time off, and recreational activities is one of the keys to success. Too many people get so Gung-Ho that they work twenty four seven and then wonder why they do not feel good, or why there family does not have as much excitement about what they are doing as they do. Take a step back and make sure that you are super focused when you are working, but that you are not working all the time.
Enjoy! Literally.
